Replace the {user_id, ip} claim pair with {keyId, uid}:
- keyId is a 32-byte random id that points to a row in the new
jwt_sessions table holding the real user id, bound IP, UA hash,
TokenVersion and expiry.
- uid is the user id encoded through pkg/idcodec; mismatch between
claim uid and session.UserID trips WAF block on the caller IP.
- identityHandler now rejects unknown/revoked/expired sessions, IP
drift and stale TokenVersion. Refresh updates session.ExpiresAt.
User.TokenVersion bumps on password change and revokes outstanding
sessions, so a leaked JWT secret alone is no longer enough to forge
a token. JWTSession rows are GC'd every 10 minutes (expired + grace
or revoked >24h). OAuth2 callback shares the same issue path.
Includes regression tests for happy path, mismatched claim uid,
revoked session, TokenVersion bump, IP drift and unknown keyId.
