Fix Monday.com push failures and improve error visibility

- Fix toast showing success when all cards fail (now shows error/warning)
- Fix column value formatting: booleans use checkbox format, JSON arrays
  join as comma-separated strings, objects serialize properly
- Filter out empty/null/undefined string values before sending to API
- Add verbose logging to Monday.com GraphQL client for debugging
