feat: add primary badge selection for user profiles

Implements #49 - Allow users to select one primary badge to display
on their profile instead of showing all badges at once.

Changes:
- Add PrimaryBadge enum to Prisma schema and shared types (STAFF, MOD, VIP, DISCORD)
- Add primaryBadge field to User model and all user interfaces
- Update settings component with badge selection dropdown
- Only show badges the user actually has in the dropdown
- Update profile component to display only selected badge (or all if none selected)
- Add primaryBadge to admin profile edit modal
- Update API routes and services to handle primaryBadge
- Export PrimaryBadge enum from shared-types (not just as type)

Additional fixes:
- Fix Angular output naming: rename onEdit/onDelete to edit/delete
- Update all parent components using comment-display outputs
- Add type casting for Prisma PrimaryBadge enum to shared-types enum
