ai: restore the quota probe on Codex, rewrite the footer

The Codex migration left /usage returning 501 and no quota signal for the governor. Codex does expose one after all — it just isn't an HTTP endpoint. Probe: `codex app-server` is a JSON-RPC-over-stdio surface whose `account/rateLimits/read` returns the same snapshot the interactive TUI shows. Handshake is initialize -> `initialized` NOTIFICATION -> read; without the notification the read never answers. adolf-llm's /usage now drives that and normalises the result. Shape change, and why the consumers had to be rewritten rather than repointed: Kimi reported fixed buckets (window_5h / weekly / window_7d). Codex reports up to two plan-defined windows, `primary` (long) and `secondary` (shorter burst, often null), so the payload is now {plan, pct, primary, secondary, limit_reached} with each row as {pct, window_mins, window_label, resets}. `pct` is the max across live windows — the single number a gate can read without knowing which window binds. Probing spawns a codex process (~2s), so results are cached in memory and on the workspace volume with a 5min TTL, concurrent probes are de-duped, and a failed refresh serves the last good reading tagged stale/as_of/age_s rather than nothing. ?force=1 bypasses the TTL. kimi-quota-footer-plugin -> codex-quota-footer-plugin (id, mount path and the openclaw.json entry key all renamed together — they must agree or the plugin silently fails to load). It now renders whatever windows the plan actually has, shortest first, and flags limit_reached and stale readings. quota-command updated for the same payload. Verified: /usage returns live data (30d 4%, plan free), warm cache serves in 17ms vs ~2s cold, the gateway reaches the route, adolf loads codex-quota-footer, and the formatter degrades to no footer on empty/null payloads instead of breaking the reply. Note: the account reports planType "free", not a paid ChatGPT plan. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_014Y5QPagv4iun1ghpwM96Ff
