test(handlers/socket): add socket_test.go — 6 cases for Phase 30.1/30.2 auth gate

Tests SocketHandler.HandleConnect WebSocket upgrade auth logic:

1. Canvas client (no X-Workspace-ID) → bypasses auth, no DB calls
2. Agent with no live tokens → grandfathered through, no bearer check
3. DB error on HasAnyLiveToken → 500 Internal Server Error
4. Live token present, missing Bearer header → 401 Unauthorized
5. Live token present, invalid Bearer token → 401 Unauthorized

Uses sqlmock for DB expectations + miniredis for wsauth token subsystem.
Hub.Run() drains the Register channel so WS upgrade attempts don't block.

Issue: #699
