[Epic] LR-6 · Moderation, Safety & Room-Version Correctness

[Deniel9204]

Make moderation actually work and safe: fix silent permission failures, add unban, client-level ignore/block, content reporting, history-visibility control, and proper v6/v11/v12 handling.

Why it's long-running: Combines correctness fixes (PL evaluation, version-aware roles), new moderation surfaces (unban, reasons, reporting), account-wide safety (m.ignored_user_list, CSAM), and room-version selection — spanning rooms, settings, and the timeline.
