feat: enhance risk pool management and role validation

- Updated AGENTS.md to streamline information on risk pool operations and agent account restrictions.
- Introduced filtering options in AdminRiskPoolIndexController for active risk pools.
- Refactored AdminRiskPoolLockLogIndexController to support grouping by ticket or entry.
- Enhanced AdminRoleStoreController and AdminRoleUpdateController to prevent the use of reserved slugs for new roles.
