Prototype administrative discussion mute controls

Let owners/operators mute or unmute new public/private sends from a human seat while retaining history, incoming messages, gameplay and credentials. Fence metadata and durable audit writes with live authority, membership and versions. Preserve exact admin/message retries and inherit restrictions through seat recovery.

Validation: types/lint, 5431 offline tests, build, 52 HTTP integration tests, 24 administrator HTTP groups, independent SQL/privacy/UI review and desktop/mobile refresh acceptance. All 2230 prior games and 4746 seats preserved. Additive migration 0016. Verified runtime fingerprint 588967fbb9c2e3b6abe2990c4fce96ee69e2256fb7e3ee416314b87593cebba9; documentation-only grammar/button-label review gives b5e57bdd26812debede91c588e38f247f1fa895ad23e7ae30bc8550eedcd90ec. New-revision deployed acceptance remains open; full admin/rules scope is unfinished.

 ## Current checkpoint and work
 
-Current work adds [participant AI support](ADMIN_PARTICIPANT_AI.md): a live
-owner/operator can enable an existing AI difficulty for an eligible human in a
-paused, started game. Saved custody and seat access remain; the human can take
-back control, and resume is separate. Atomic audit, exact saved retries and
-commit-time room/seat/authority checks are connected. Participant restrictions,
-access revocation, assisted recovery, permanent deletion, bulk actions and
-backup/operations tools remain unfinished. This adds no strategic AI refinement.
+Current work adds [discussion moderation](ADMIN_DISCUSSION.md): owners/operators
+can mute or unmute new public/private messages from a human seat. History,
+incoming messages, game state and credentials remain saved; the setting follows
+recovery/handover. Atomic authority/version fences, durable audit and exact
+admin/message retries are connected. This is partial participant support;
+access revocation, participant removal, assisted recovery, permanent deletion,
+bulk actions and backup/operations tools remain unfinished.
