Refactor task management and add attachment functionality

- Updated task editing template to handle default status for new tasks and corrected variable names.
- Enhanced work time reporting by rounding time to the nearest quarter hour and adjusting amount formatting.
- Introduced TasksController to manage task-related operations, including status resolution and email notifications.
- Added TaskAttachmentRepository for handling task attachments, including upload, rename, and delete functionalities.
- Implemented WorkTimeRepository to fetch clients with unsettled tasks and calculate total work time.
- Created unit tests for TasksController and TaskAttachmentRepository to ensure functionality and correctness.
