feat(admin): add RoleBadge component and integrate it in user management views

- add new RoleBadge shared component for consistent role display
- export RoleBadge from shared components index
- replace inline Badge usage with RoleBadge in UsersPage role column
- use RoleBadge via renderTag prop in UserEditModal role TagInput
- simplify TagInput Pill to a generic unstyled pill, removing color logic
