refactor(role): refactor role management API and service

- Remove unused imports and simplify controller annotations
- Change request mapping path from /api/role to /api/roles
- Update assignRolesToUser endpoint to use POST /users
- Update revokeRolesFromUser endpoint to use DELETE /users
- Modify getAllRoles method to return OptionResponse instead of RoleResponse
- Simplify database query in RoleServiceImpl using lambda query wrapper
- Add proper authorization checks for all role management endpoints
- Remove redundant getUserRole method with duplicate logic
