v2 Phase 4: decouple Session (local usage) from the rate-limit API

Browse Source 
The Session screen's tokens/cost are computed locally from transcripts and need
no network, but they were gated behind a successful rate-limit API call — so an
expired OAuth token or API outage froze the whole watch.

Daemon: always compute and send local usage every cycle; rate-limit utilization
is now best-effort and merged on top when available, with ok=true only when it's
fresh (ok=false on expired token / API down). poll_api returns just the
rate-limit fields; connect_and_run owns the payload + ok flag.

Firmware: ui_update always refreshes the Session screen; the rate-limit bars and
the freshness clock update only when data->ok, so the usage view falls back to
its existing idle "Zzz" state instead of showing stale or zeroed percentages.

Verified: with the token expired (HTTP 401) the daemon still sends
tk/tc/tn/to + ok:false and the Session screen keeps updating.
