refactor: update mass edit dialog and introduce new select components

- 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.

+ * Does not include spec generation, approval, or require-approval checkbox.

+ * @example
+ * ```tsx
+ * <PlanningModeSelect
+ *   mode={planningMode}
+ *   onModeChange={(mode) => {
+ *     setPlanningMode(mode);
+ *     setRequireApproval(mode === 'spec' || mode === 'full');
