fix(resolution): resolve this.<field>.<method>() on the fields declared type (#1496) (#1792)

Land the six-file fix from upstream PR #1691 by danusha2345
(pr-1691 at 6d0e80d52ae953b22d615bd20c4a4c7758814e60), preserving
wasm/native extraction parity and exclusive field-type resolution.

Preserve coexistence with the #1566 Map/collection fix merged in #1790,
including nested holder.values.get coverage and the unchanged #1566
Unreleased changelog bullet. EXTRACTION_VERSION remains unchanged.

Align the existing chained-receiver regression with the fix: a declared
service field calls its method, while an anonymous field type does not
bind to unrelated same-named project functions.

Verified on Linux with Node 22.19.0:
- Rebuilt the native kernel and TypeScript/browser distribution.
- Both backends change Outbox::send -> Outbox::send into
  Outbox::send -> Mailer::send, keep Relay::forward -> Mailer::send,
  and store no self-edges in the issue repro.
- Wasm: 224 tests passed; native kernel: 255 tests passed, no skips.
- All 10 #1566 resolution cases pass on each backend, plus all four
  nested-receiver extraction parity cases.
