fix(sync): resolve correct DB path + ensure sync tables before force push

- getDbPath() now checks context.db first (where CLI/MCP write frames)
- ensureSyncTables() called at start of push/pull (not just in helpers)
- Fixes crash on `push --force` when cloud_sync_state table doesn't exist
- Skip missing tables (trace_events, entity_states) gracefully
- Removed stale PROVENANT_API_KEY from .env (env var precedence bug)
- Successfully synced 651 entities to Provenant cloud
