refactor: unify member dialogs into reusable BulkMembersDialog component

- Merge AdmitPendingMembersDialog and SetBulkVisibilityDialog into single BulkMembersDialog
- Add dynamic props for dialog type, title, description, button text, and empty state
- Support both 'admit' and 'visibility' modes with conditional behavior
- Rename setVisibilityForSelectedMembers to addContactWithVisibility for clarity
- Update success counting to track contacts added vs visibility set
- Improve error messages to reflect primary action of adding contacts
- Update MembersList to use unified dialog with role-based configuration
- Remove unused libsUtil import from MembersList
- Update comments and method names to reflect unified functionality
- Rename closeMemberSelectionDialogCallback to closeBulkMembersDialogCallback

This consolidation eliminates ~200 lines of duplicate code while maintaining
all existing functionality and improving maintainability through a single
source of truth for bulk member operations.
