232a48482b MM-69057: Verify post ownership on inbound shared-channel edit/delete (#36814)
The inbound shared-channel sync handler applied edits and deletes from a
remote cluster without checking that the existing post belonged to that
remote, allowing a remote to modify or delete posts it did not own.

Enforce the same ownership check already used for reactions and
acknowledgements before editing or deleting a synced post, and add
regression tests for the cross-remote cases.
