docs: handover reflects the deployed and rehearsed state

Deployed to el3ab-player and verified end to end against production with
tests/rehearsal.mjs, which now also covers spectating and the "watch this player"
lookup. Production is left byte-for-byte as it was found: row counts across
matches, tournaments, profiles, rating_history and the queue are unchanged.

Remaining for a human: play one game on a real device (the interface changes are
the part I could not verify), and optionally set CRON_SECRET and
SUPABASE_JWT_SECRET, which need CapRover app configuration the push webhook does
not grant.

-- **I did not open the app in a browser.** The API and the engine are covered thoroughly; the

-  look at first.
