feat(dashboard): scoped API keys with rate limits and quotas

Bearer keys (dlk_...) are checked per request against their owner's current account (ban, lock, demotion, sign out everywhere stop or narrow them at once) and their scope: permission routes need the permission in scope, read-only keys only read, level-only routes need an all-permission key, and session-only paths (sign-in, password, 2FA, key management) are never reachable with a key. Per-key rate limit and daily quota with 429 and X-RateLimit/X-Quota/Retry-After headers; usage is written in batches every minute. WebSocket subscriptions honour the scope too. Routes to list, make, rotate and revoke keys; staff with api_keys_manage can see and revoke others' keys under the rank rules. POST /api/auth/token now makes an all-permission key. Audit entries for create/rotate/revoke/denied, and actions done with a key are attributed to "user (key name)". Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
