fix(extraction): land upstream declaration initializer walks (#1511) (#1802)

Squash danusha2345's PR #1511 at d282f9e8 onto main 8c9c4761,
preserving its nine non-merge commits and main's existing Unreleased notes.
Calls in Kotlin, Java, TS/JS, Scala, Rust and Python declaration initializers
now retain the owner established by the upstream regression expectations.
Include the upstream CFML, dynamic-dispatch summary and viewer follow-ups.

Linux fail-to-pass validation (Node 22.19.0, rebuilt dist and native kernel):
- Before: TS load belonged to file:app.ts; Python/Kotlin/Scala/Rust calls
  vanished; Java lost the field-lambda, anonymous override and eager calls.
- After: all six languages PASS; 12 native/WASM LF/CRLF parity checks PASS.
- Focused initializer regressions: 10 passed with CODEGRAPH_KERNEL=0 and
  10 passed with the kernel enabled; Kotlin's grammar fallback is recorded.
- Related regression suites: 879 passed, 1 skipped across 15 test files.
- Evidence: /workspace/cg-1510-repro/before and /workspace/cg-1510-repro/after
  (combined test output: after/vitest.log).

Fixes #1510
Supersedes #1511
