feat(02-01): add CRUD form actions

- Add create action with content validation (title optional, type defaults to thought)
- Add update action with field-by-field updates and validation
- Add delete action with existence check
- Add toggleComplete action to toggle between open/done
- Use getOrdered() in load function for tasks-first ordering
- Update page component to use new data structure
