feat(api, web): enhance agent installation process with invited status and policy support

- Updated the agent enrollment process to include an 'invited' status, allowing for better tracking of agent states.
- Implemented support for install links that can now include an `install_link_id`, facilitating the transition from invited to pending status upon enrollment.
- Enhanced the MikroTik installation script to include the `EvofwInstallLinkId` for better tracking and management.
- Added new API endpoints for fetching agent policies and serving MikroTik-specific installation scripts.
- Improved the web UI to reflect the new agent statuses and provide copyable installation commands for agents.
