feat(api, web): implement policy mode management for agents and rules

- Added support for policy modes ('blacklist' and 'whitelist') in agent and policy set management.
- Updated API endpoints to handle policy mode during agent assignment and rule operations.
- Enhanced the web UI to display and manage policy modes for agents and rules, ensuring all assigned sets share a consistent mode.
- Introduced new validation to enforce single policy mode across assigned sets for agents.
- Improved error handling for policy mode conflicts and updated documentation accordingly.
