refactor(auth): simplify authorization checks to use membership only

- Remove explicit ADMIN role checks in API handlers
- Replace combined creator/member role checks with membership-only filters
- Update seed data roles to reflect changed authorization logic
- Add migration to insert hunt creators as members for consistent checks
- Prevent removal of hunt creator as a member with new explicit check
- Adjust related user role updates and queries accordingly
- Upgrade dependencies including nuxt and zod for compatibility
