Remove remaining status_id references after in_progress migration

- Remove Preload("Status") from worker handler and repositories
- Update seeds to use in_progress boolean instead of status_id
- Remove task_taskstatus table creation from lookup seeds
- Update documentation to reflect in_progress boolean pattern

Fixes notification worker error:
"Status: unsupported relations for schema Task"
