- Remove task_statuses lookup table and StatusID foreign key
- Add InProgress boolean field to Task model
- Add database migration (005_replace_status_with_in_progress)
- Update all handlers, services, and repositories
- Update admin frontend to display in_progress as checkbox/boolean
- Remove Task Statuses tab from admin lookups page
- Update tests to use InProgress instead of StatusID
