feat: migrate persistence from JSON to SQLModel (Phase 1)
- Integrated SQLModel with SQLite for robust data persistence - Refactored UserManager and WatchlistManager to use SQL queries - Migrated models to SQLModel with relationships and primary keys - Updated test suite with in-memory database isolation - Removed deprecated JSON storage files
