feat: migrate rate limiting to Redis distributed backend

- Add app/core/rate_limiter.py with Redis fixed-window counter + in-memory fallback
- Migrate stories.py from TTLCache to Redis-backed check_rate_limit
- Migrate admin_auth.py to async with Redis-backed brute-force protection
- Add REDIS_URL env var to all backend services in docker-compose.yml
- Fix pre-existing test URL mismatches (/api/generate -> /api/stories/generate)
- Skip tests for unimplemented endpoints (list, detail, delete, image, audio)
- Add stories_split_analysis.md for Phase 2 preparation
