feat: implement cache-aside layer with Redis cache interface, cache keys, TTL policies, and tests
- Created cache/store.go with Cache interface, redisClient wrapper, cacheStore, TTL constants (CityTTL 30d, SearchNearTermTTL 3h, SearchFarTermTTL 7d)
- Implemented cache keys: cities:{code}, stations:{id}, search:{from}:{to}:{date}
- Implemented cache-aside pattern via CacheAside struct with GetOrSetFuncPattern, GetCity, GetStation, GetSearch
- Added TTL-aware search result caching with near-term (3h) and far-term (7d) policies
- Wrote 6 unit tests: CacheGetSet, CacheKeyString, CacheAsideGetOrSet, CacheAsideGetCity, CacheAsideGetSearch, CacheInvalidate
- All tests pass with Redis integration
