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).

The review asked for a regression test pinning DTD-prohibited parsing. Writing
it showed the premise was wrong: XDocument.Parse permits an internal DTD subset
and expands its entities, so a DOCTYPE-bearing response body parsed fine and the
guard did not exist (entity-expansion DoS on external input).
Parse now goes through XmlReader with DtdProcessing.Prohibit and a null
XmlResolver. The regression test feeds a DOCTYPE + ENTITY payload shaped as a
well-formed EWS error response, so it fails if DtdProcessing is ever loosened
rather than passing for the unrelated-XML reason.
