app/v2.12.1

• Added Porkbun, Namecheap and Njalla as ACME DNS providers
• Fixed slow reconnection after the client has been idle or asleep, most noticeable on mobile devices. The server now sends QUIC stateless resets, so a client holding a stale connection reconnects immediately instead of waiting out its idle timeout
• Fixed mimic refusing to start when its optional kernel module is not loaded
• Various dependency updates
