Server 2.4.0, app 2.11.1: ABRP forwarding removed from the server

The car sends live data to ABRP itself, and the car and the server go
over the same mobile connection: when the car cannot reach ABRP, it
cannot reach the server either, so the server's fallback bought
nothing. The forwarder, its ABRP_* settings and abrpSentUtc are gone;
the server only stores. The app stops sending abrpSentUtc (the server
ignores unknown fields, so 2.11.0 keeps working) and its texts no longer
promise a server fallback.

 3. **Registry access.** The `mg4-server` package on git.stinnesbeck.com is public, so no pull
    secret is needed. If you make it private, add an `imagePullSecrets` entry to `server.yaml`.
