Auto-Delete Tailscale Machines When Server is Deleted

Description:

When a server is deleted in dFlow, automatically remove the associated Tailscale machine from the Tailscale network. This ensures that no orphaned devices remain connected and avoids potential security or network clutter issues.

Acceptance Criteria:

• Detect Tailscale device(s) linked to a server upon deletion.

• Automatically remove those devices from Tailscale.

• Confirm deletion was successful and log the action.

• Handle cases where the Tailscale device is already missing gracefully.

Benefits:

• Maintains a clean and secure Tailscale network.

• Prevents unused devices from consuming Tailscale node slots.

• Reduces manual cleanup after server removal.
