Cal Corum f6e8ab5f67 Add integration tests for WebSocket game flow (TEST-002)
Create 16 integration tests across 7 test classes covering:
- JWT authentication (valid/invalid/expired tokens)
- Game join flow with Redis connection tracking
- Action execution and state broadcasting
- Turn timeout Redis operations (start/get/cancel/extend)
- Disconnection cleanup
- Spectator filtered state
- Reconnection tracking

Uses testcontainers for real Redis/Postgres integration. Completes
Phase 4 (Game Service + WebSocket) with all 18 tasks finished.

"""Integration tests for WebSocket game flow.
This module tests the end-to-end game flow through the Socket.IO handlers
with real testcontainer-backed Redis and Postgres. While the Socket.IO
transport is mocked, all game logic, state persistence, and service
interactions use real implementations.
Test Categories:
- Authentication flow with real JWT validation
- Game join/rejoin with real state persistence
- Action execution with real game engine
- Turn timeout with real Redis timers
- Reconnection with real connection tracking
- Opponent notifications with real state lookups
Why Integration Tests Matter:
These tests catch issues that unit tests miss:
- Database constraint violations
- Redis serialization issues
- Service coordination bugs
- Race conditions in state updates
