fix: resolve 30+ bugs from security audit

Critical:
- CORS: replace allow_any_origin + credentials with env-configured origins
- XSS: escape HTML before dangerouslySetInnerHTML in search results
- Path traversal: sanitize storage keys to reject ".." components
- Auth missing: add Session requirement to git init/open/is-repo endpoints
- Transaction: wrap issue cascade delete in DB transaction

High:
- Mutex poisoning: replace unwrap() with poison-recovering guards
- Drop tokio::spawn: use runtime handle or fallback thread for lock release
- Redis KEYS: replace with non-blocking SCAN for typing events
- SSH panic: handle missing stdin/stdout/stderr gracefully
- LFS auth: remove x-user-uid header injection vector, generate per-request tokens

Medium:
- Memory leak: remove Box::leak in provider normalization
- Race conditions: query closed count directly instead of subtraction
- Silent failures: add tracing::warn for AI tasks, room events, activity logs
- Frontend nav: sync activeRoomId when initialRoomId prop changes
- Duplicate nav: remove redundant setActiveRoom in delete handler
- Callback conflict: skip undefined values in updateCallbacks merge
- Stale closure: use wsClient state instead of wsClientRef.current in useMemo

Low:
- Captcha: validate captcha not empty before login submission
- Broadcast capacity: reduce from 100K to 1000
- Error handling: add try/catch for removeMember and updateMemberRole
- Loading state: show placeholder instead of null in RepositoryContextProvider
- WebSocket: add heartbeat ping and jitter to reconnect backoff
