- Removed advanced options toggle and related state from the mass edit dialog for a cleaner UI.
- Replaced ProfileQuickSelect with ProfileSelect for better profile management.
- Introduced new PlanningModeSelect and PrioritySelect components for streamlined selection of planning modes and priorities.
- Updated imports in shared index to include new select components.
- Enhanced the mass edit dialog to utilize the new components, improving user experience during bulk edits.
