The refresh button had no effect because two independent gates blocked
the Codex probe:
1. isOpenAICodexSnapshotStale returned false for non-WS-v2 accounts even
when data was stale — this is correct for background auto-refresh (Codex
quota is only auto-tracked for Codex CLI / WS v2 accounts), so this
behavior is preserved.
2. shouldProbeOpenAICodexSnapshot had a 10-min in-memory rate limit with
no bypass for explicit user requests.
Fix: add a force parameter threaded from handler → GetUsage → getOpenAIUsage
→ shouldProbeOpenAICodexSnapshot. When force=true (manual refresh button),
both gates are bypassed and the probe always runs. Background auto-loads
continue to respect the original WS v2 logic and 10-min rate limit.
