MikroTik VPN Manager

Adds the parts of MikroTik VPN that clients and staff use every day.

- Clients download their WireGuard configuration or scan a QR code with the WireGuard app
- Downloads are private: only the client who owns the service can get them, and nothing is cached
- A staff overview of every VPN account and router, with a connection check
- Clean up an account that needs attention with one click

Needs the MikroTik VPN server module from the Marketplace.
