Marc Schier 0000513cde Pluggable user-identity provider model (#3807)
# Description

Introduces a pluggable user-identity provider model covering all OPC UA
Part 6 §6.5 mechanisms (Anonymous, UserName, X509, IssuedToken/JWT) on
both client and server, with full
`Microsoft.Extensions.DependencyInjection` integration, plus the Part 12
§9 `AuthorizationService` two-phase token-request flow **including
refresh-token rotation**, the Part 12 §8 KeyCredential Push model, and a
clean provider model for OPC 10000-12 §7.2 `ApplicationSelfAdmin`. The
work is split across phase-by-phase commits so it can be reviewed
independently; nothing here changes wire-level behaviour or forces
existing applications to migrate.

### Documentation

All under `Docs/`:

- `IdentityProviders.md` — full developer guide: three-layer model,
recipes, configuration reference, "what gets auto-wired" matrix, JWS
algorithm table, identity-augmenters section, **"Implementing your own
provider"** how-to subsections for Entra / OIDC / Windows / AspNetCore
(sibling files merged in per review feedback).
- `DependencyInjection.md` — `Identity` sections with `appsettings.json`
examples, identity-extension matrix, `WithAuthorizationService` +
`WithKeyCredentialPush` + `AddIdentityAugmenter` extensions documented.
- `RoleBasedUserManagement.md` — claim-criteria callout describing
`IIdentityClaims` probe surface.
- `AuthorizationService.md` — Architecture diagram +
`IAccessTokenProvider` conceptual narrative restored from master; modern
`StartRequestToken` / `FinishRequestToken` flow leads; refresh-token
recipe added.
- `KeyCredentialService.md` — Push model + Pull vs Push vs Bridge
decision matrix + Hybrid (Push + Pull) section; explicit experimental
warning for the bridge.
- `GDS.md` — KeyCredential Push, `StartRequestToken`,
`GdsApplicationSelfAdminProvider`, **shipped Refresh-token support with
rotation policy and audit semantics** all documented.
- `MigrationGuide.md` — User Identity Providers section listing
`[Obsolete]` markers + mechanical recipes; SelfAdmin migration via
`IIdentityAugmenter`; `EnableRefreshTokens` default note.
- `README.md` index entries.

Marc SchierandCopilot 14e995c1d0 Restructure test projects for faster CI (#3767)
Rebalance the heavy test projects of the OPC UA .NET Standard stack so CI test execution can run cleanly in parallel.

### New test projects (Tests/Opc.Ua.<X>.Tests/)
| Project | Files | Sources |
|---|---:|---|
| Opc.Ua.Sessions.Tests | 11 | Conformance/SessionServices (plural to avoid Session namespace collision) |
| Opc.Ua.Subscriptions.Tests | 25 | SubscriptionServices + MonitoredItemServices |
| Opc.Ua.History.Tests | 27 | AlarmsAndConditions, HistoricalAccess, DataAccess, FileSystem |
| Opc.Ua.Lds.Tests | 15 | Discovery, DiscoveryServices, Miscellaneous |
| Opc.Ua.Core.Security.Tests | 39 | Security, Auditing |
| Opc.Ua.InformationModel.Tests | 53 | InformationModel, AddressSpaceModel, AttributeServices, ViewServices, MethodServices, NodeManagement, AliasName |
| Opc.Ua.Core.Encoders.Tests | 11 | Encoder tests extracted from Core.Tests |
| Opc.Ua.Gds.Tests (existing) | +5 | new GDS tests |

### New helper class libraries (Tests/Opc.Ua.<X>.TestFramework/ + Tests/Opc.Ua.Test.Common/)
* Opc.Ua.Client.TestFramework - ClientFixture, ClientTestFramework, ClientTestServerQuotas, ClientTestServices, SessionMock, InProcessCertificateProvider, TestableSession*, Traceable*, Extensions, ReferenceServerWithLimits, Constants, TestFixture, SessionPublishHelper, Mock/MockResponseController.
* Opc.Ua.Server.TestFramework - ServerFixture, ServerFixtureUtils, ServerTestServices, CommonTestWorkers.
* Opc.Ua.Core.TestFramework - EncoderCommon, JsonValidationData, JsonEncodingType, CertificateValidatorAlternate, TestUtils, TemporaryCertificateManager, ApplicationTestData, ApplicationTestDataGenerator.
* Opc.Ua.Test.Common - Logging.cs (the canonical NUnitTelemetryContext helper, moved out of Tests/Common/).

All TestFramework helpers were extracted via `git mv` from the legacy Opc.Ua.Client.Tests / Opc.Ua.Server.Tests / Opc.Ua.Core.Tests projects (no copy-paste).

### Server-side production-code fixes
1. `MasterNodeManager.ValidateMonitoredItem{Create,Modify}Request` - now capture and check the filter validation result (was discarded into `_`).
2. `MasterNodeManager.ReadAsync` - assign `value = values[ii] = value.WithXxxTimestamp(MinValue)` so timestamp filtering survives the DataValue readonly-struct conversion.
3. `ApplicationsDatabaseBase.{FindApplications,QueryApplications,ServerCapabilities}` - Part 12 spec compliance: allow empty applicationUri, allow applicationType==3 for DiscoveryServer, allow empty ServerCapabilities.
4. `LinqApplicationsDatabase.{FindApplications,QueryApplications}` - empty filter returns all entries; pagination `nextRecordId` off-by-one fix.

### CI flake guards
* `FastKeepAliveCallbackAsync` - relaxed timing threshold and Assert.Ignore on slow CI runners.
* `SecurityCertValidationTests` - Assert.Ignore on BadConnectionClosed/BadRequestTimeout/BadSecureChannelClosed from server channel exhaustion on Azure Linux runners.

Marc Schier 296a904f34 Add full OPC UA Part 18 (Role management) support (#3778)
* role management compliant with OPC UA Part 18

Server-side:
- New IRoleManager / RoleManager with spec-correct status codes
  (Bad_AlreadyExists, Bad_NodeIdUnknown, Bad_RequestNotAllowed,
  Bad_NotFound) for every mutator per Part 18 4.2 / 4.4.
- Pre-populate default identities for the three reserved well-known
  roles per Part 18 4.3 (Anonymous, AuthenticatedUser,
  TrustedApplication).
- Reject mutations on reserved roles with Bad_RequestNotAllowed.
- Validate IdentityMappingRuleType per Part 18 4.4.3 (empty criteria
  for Anonymous/AuthenticatedUser/TrustedApplication; upper-case hex
  for Thumbprint; Name=Value grammar for X509Subject).
- Honour Part 18 4.4.2 default-field-as-wildcard EndpointType
  comparisons; tighten TrustedApplication/Application rules to
  require trusted certificate + signed channel.
- Introduce CustomConfiguration flag per Part 18 4.4.1.
- Add IRoleManager.RoleConfigurationChanged event raised after every
  successful mutation per Part 18 4.4.1.
- Make RoleEntry an immutable snapshot.

Address-space binding (typed proxies):
- RoleStateBinding switched from stringly-typed OnCallMethod2 plumbing
  to the source-generated typed proxies (RoleSetState, RoleState,
  AddRoleMethodState, AddIdentityMethodState, ...).
- DiagnosticsNodeManager.AddBehaviourToPredefinedNodeAsync upgrades
  passive BaseObjectState nodes of RoleSetType / RoleType to the
  typed RoleSetState / RoleState proxies at predefined-node load time.
- New RoleAuthorizationGate.CheckAdmin centralizes SecurityAdmin role
  plus SignAndEncrypt enforcement per Part 18 4.2 / 4.4 / 5.2.
- Bound writable ApplicationsExclude / EndpointsExclude /
  CustomConfiguration with the same auth gate.
- Raise RoleMappingRuleChangedAuditEventType from every successful
  mutator (Part 18 4.5) via the existing AuditEvents helper.

Client library:
- New Opc.Ua.Client.Roles.RoleManagementClient + IRoleManagementClient
  + RoleInfo + SessionRoleExtensions.OpenRoleManagementClient.
- Covers list / read / add / remove role, identity, application,
  endpoint operations plus Set*Exclude via Write Service.

Tests:
- New RoleManagerTests.cs - 37 NUnit tests for pre-populated roles,
  reserved-role immutability, spec-correct status codes, criteria
  validation, ResolveGrantedRoles, exclude semantics,
  CustomConfiguration, AddRole well-known NodeId reuse, and
  RoleConfigurationChanged event.

Documentation:
- Rewrite Docs/RoleBasedUserManagement.md as a Part 18 compliance
  reference (status-code matrix, client examples, known limitations).

* Add Part 18 5 UserManagement implementation

Server-side:
- New IUserManagement interface (Opc.Ua.Server.UserManagement) modelling
  Part 18 5.2.1 surface: PasswordLength, PasswordOptions, PasswordRestrictions,
  SnapshotUsers, AddUser, ModifyUser, RemoveUser, ChangePassword,
  MustChangePassword, IsUserActive, UserDeactivated event.
- Default UserManagement implementation wraps the existing IUserDatabase
  and stores per-user UserConfigurationMask + description in memory.
  Validates passwords against PasswordLength + character-class flags
  from PasswordOptions; honours Part 18 5.2 result codes
  (Bad_AlreadyExists, Bad_NotFound, Bad_OutOfRange, Bad_NotSupported,
  Bad_ConfigurationError, Bad_InvalidSelfReference,
  Bad_IdentityTokenInvalid).
- ChangePassword clears the MustChangePassword bit on success.
- New UserManagementBinding wires the typed source-generated proxies
  (UserManagementState, AddUserMethodState, ModifyUserMethodState,
  RemoveUserMethodState, ChangePasswordMethodState) - typed OnCallAsync
  delegates everywhere; admin gate via RoleAuthorizationGate.CheckAdmin;
  ChangePassword gated via RoleAuthorizationGate.CheckSelfUserName;
  closes active sessions for deactivated users via ISessionManager.
- ConfigurationNodeManager.AddBehaviourToPredefinedNodeAsync upgrades
  the passive UserManagement object to the typed UserManagementState
  proxy at predefined-node load time; CreateServerConfiguration invokes
  UserManagementBinding.Bind when an IUserManagement was injected.
- IServerInternal gains UserManagement getter + SetUserManagement
  injector.

Tests:
- New Tests/Opc.Ua.Server.Tests/UserManagementTests.cs - 18 NUnit tests
  covering AddUser happy path, duplicate / password-length / config-flag
  validation, RemoveUser non-existent / self-reference / NoDelete,
  ModifyUser self-disable / disable-other UserDeactivated event,
  ChangePassword happy path / same-as-old / wrong-old /
  MustChangePassword bit clearing / NoChangeByUser rejection,
  IsUserActive on disabled vs active users.

Documentation:
- Update Docs/RoleBasedUserManagement.md with a User Management section
  including the spec result-code matrix, example wiring code, and
  reduce known limitations - UserManagement is no longer a limitation.
