Fix Trello closed boards bug - filter API and clear stale cache

Closed boards were appearing because:
1. API fetched all boards including closed ones
2. Cache used upsert logic that never removed old data

Fixes:
- Add filter=open to GetBoards API call
- Add filter=visible to GetCards API call
- Clear boards/cards tables before inserting fresh data in SaveBoards
