0.12.1: Telegram Fast Status

• The optional Telegram status row now appends lowercase fast for the active Codex model, or shows fast alone when quota is unavailable. It rereads the per-model preference at menu render time, so toggles, model changes and manual edits do not wait for quota refresh. Quota polling, auth, request adaptation and terminal behavior are unchanged; isolated tests cover enabled/disabled state, model/provider changes and unreadable configuration.
