Merge 3b262cf180 into 89def9aee6

This commit introduces a multi-server architecture to the Sanai panel, allowing you to manage clients across multiple servers from a central panel.

Key changes include:

- **Database Schema:** Added a `servers` table to store information about slave servers.
- **Server Management:** Implemented a new service and controller (`MultiServerService` and `MultiServerController`) for CRUD operations on servers.
- **Web UI:** Created a new web page for managing servers, accessible from the sidebar.
- **Client Synchronization:** Modified the `InboundService` to synchronize client additions, updates, and deletions across all active slave servers via a REST API.
- **API Security:** Added an API key authentication middleware to secure the communication between the master and slave panels.
- **Multi-Server Subscriptions:** Updated the subscription service to generate links that include configurations for all active servers.
- **Installation Script:** Modified the `install.sh` script to generate a random API key during installation.

**Known Issues:**

- The integration test for client synchronization (`TestInboundServiceSync`) is currently failing. It seems that the API request to the mock slave server is not being sent correctly or the API key is not being included in the request header. Further investigation is needed to resolve this issue.
