Two root causes prevented bots from making any moves:
1. SignRequest signing string included timestamp ({match_id}.{turn}.{timestamp}.{hash})
but all bots implement verifySignature without timestamp ({match_id}.{turn}.{hash}).
Fixed by dropping timestamp from the signing string; X-ACB-Timestamp header is still
sent for clock-skew checks but not in the HMAC.
2. The API stores bot secrets AES-GCM encrypted (184 hex chars) in the DB. The worker
was passing the ciphertext directly as the HMAC key, while bots use their plaintext
k8s secret (64 hex chars). Fixed by decrypting in the worker using ACB_ENCRYPTION_KEY.
Also tightens the home page winner filter to exclude winner_id="0" stalemates.
