docs(src): fix CommentChecker findings across src/ — 1,032 → 5 (all false positives)

Comment/XML-doc changes only, no code logic:
- strip project-tracking references (WP*, P*-*, row-NN, #NN, Task N) from
  comments, keeping the explanatory rationale
- add missing summaries, <param>, <returns>, <typeparam> and <inheritdoc/>
- replace misused <inheritdoc/> with real docs; where <inheritdoc/> was
  combined with useful remarks, move the rationale into // comments
- drop stale replicationActor <param> on DeploymentManagerActor ctor

Remaining 5 are false positives (CWE-1236 x2, failures-1, year-0001, M365).
Build 0 errors / 0 warnings.
