feat: add allocated status and project allocation to unit management

- Updated dashboard to display allocated units alongside deployed and benched units.
- Introduced a quick-info modal for units, showing detailed information including calibration status, project allocation, and upcoming jobs.
- Enhanced fleet calendar with a new quick-info modal for units, allowing users to view unit details without navigating away.
- Modified devices table to include allocated status and visual indicators for allocated units.
- Added allocated filter option in the roster view for better unit management.
- Implemented backend migration to add 'allocated' and 'allocated_to_project_id' columns to the roster table.
- Updated unit detail view to reflect allocated status and allow for project allocation input.
