This pull request modernizes the OPC UA .NET codebase and tests, removes .NET Standard 2.0 support from certificate/security code, and updates test code to use C# 12 and .NET 8+ features for clarity and maintainability.
- Certificate and BouncyCastle interop files (e.g., CertificateBuilder.cs, X509Extensions.cs, X509SignatureFactory.cs) are refactored to drop NETSTANDARD2_0 support and use modern .NET APIs and conditional compilation.
- Test code across the codebase is updated to use default, strongly-typed Parse methods, collection expressions, and improved async/await patterns.
- Exception handling and assertions in tests are modernized, and test method naming is made consistent with Async suffixes.
- The project and build files are updated to clarify Roslynator analyzer usage and remove obsolete netstandard tags.
- General code and test cleanup includes improved null safety, type safety, and removal of deprecated or unused code.
- Allow setting ReturnDiagnostics on the session factory to ensure the diagnostic settings are part of "Create" also. Set them to SymbolicIdAndText by default.
- Better logging in unit tests, now also logs to progress including exception traces, also prefixes SERVER and TEST on console to attach the logs to the server or client side.
- GDS client stability improvements to ensure client reliably reconnects between calls when connection is lost.
- Do not dispose the application certificate when it is updated from GDS client to avoid existing sessions to crash with CryptographicException. This needs more improvements later on because it is rather hacky today.
- Remove the certificate cache in CertificateFactory (as per discussion and agreement) which allowed re-enabling the older UserIdentity API
- Logging improvements here and there to analyze issues in unit tests better
* Refactor string usage for secrets (#394)
Strings are immutable and the lifetime of secrets can not be controlled.
Use byte[] or char[] instead of strings for secrets, which can be erased
after use.
* Clear pw

-Implement the support for ApplicationSelfAdmin privilege
-implement the workflow in a test to pull the trust list after sucessfully receiving a gds signed certificate.
-this authorization is described here in the OPC Spec: https://reference.opcfoundation.org/GDS/v105/docs/7.6
- move IUserDatabase + RoleBased Identity into standard Server
- subclass SystemConfigurationIdentity from RoleBased Identity for backward compatibility
- add OPC UA Spec Defined Roles to the RoleBasedIdentity
