feat: add charts table schema and migration with data backfill
- Add charts table with id, name (unique), created_at - Add chart_id FK to candles table with composite unique on (chart_id, time) - Add chart_id FK to annotations table - Custom migration handles existing data: creates 'Imported Data' chart and backfills chart_id - Recreates tables for NOT NULL constraint (SQLite limitation)
