Fix N+1 query, add database indexes, and implement award progress caching: - Fix N+1 query in getUserQSOs by using SQL COUNT instead of loading all records - Add 7 performance indexes for filter queries, sync operations, and award calculations - Implement in-memory caching service for award progress (5-minute TTL) - Auto-invalidate cache after LoTW/DCL syncs Expected impact: - 90% memory reduction for QSO listing - 80% faster filter queries - 95% reduction in award calculation time for cached requests Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
