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.

Modelled on the OAuth device authorization grant (RFC 8628) and on
only when APPROVAL_PASSWORD is set (at least 12 characters):
- POST /v1/pair/start opens a request for an installation and returns
a short user code and the /pair URL for the car's QR code;
POST /v1/pair/poll returns pending, the car's own token (once),
denied or expired. Requests live 10 minutes, in memory.
- GET/POST /pair is a script-free approval page for the phone
(strict CSP, no framing). Five wrong passwords lock approvals for a
minute.
- Each car gets its own 43-character token; only its SHA-256 is stored
(measurement "device"), and the device is persisted before the car
can collect the token. Tokens are loaded at startup, so a restart
keeps paired cars working; the server refuses to start if they cannot
be loaded.
- GET /v1/devices and POST /v1/devices/{id}/revoke, authenticated with
the approval password, list and revoke cars.
- The shared INGEST_TOKEN keeps working.
31 tests (race detector clean), govulncheck clean. Tested end to end
against InfluxDB 2.7.12: pairing, wrong password, single collection,
persistence across restarts, revocation (also across a restart), and
that InfluxDB holds only the hash.

Same endpoints, request formats, validation rules and InfluxDB layout as
the Next.js server, so the car needs no change: POST /v1/telemetry,
PUT /v1/consumption/daily, PUT /v1/charging-sessions/{id}, GET
/v1/consumption/history/{id}, GET /v1/health. The dashboard, login and
the /v1/history reads are gone; Grafana takes over the dashboards.
- Go 1.26 standard library (net/http routing, log/slog) plus the
official InfluxDB 2 client. Fails closed at startup on a missing
InfluxDB setting or an ingest token under 24 characters.
- ABRP forwarder ported: newest fresh sample, rate limited, never
queued, credentials only in the form body.
- 22 tests: validation, aggregation, forwarding, config, and the
handlers through a fake store. govulncheck clean (x/net 0.60.0,
toolchain go1.26.9).
- Image: static binary on distroless, about 11 MB, UID 65532, port
8080; the build runs vet and the tests.
- Dev shell: Go, gopls and govulncheck instead of Node.
