Fixes #8051

Two accuracy problems in the Codex quota card, both in buildCodexUsageQuotas (open-sse/services/codexUsageQuotas.ts).

1. Latent, never-used per-feature windows shown as permanent noise

ChatGPT Codex's /wham/usage advertises a latent per-feature ceiling for the spark feature (metered_feature: "codex_bengalfox") to accounts by default. For a never-used bucket the window is unanchored — used_percent: 0 and reset_after_seconds == limit_window_seconds — so it recomputes its reset as now + full_window on every fetch. It was rendered as a permanent GPT-5.3-Codex-Spark row at 100% whose reset "snaps to exactly 7 days" on every refresh, for a model the operator never used (ChatGPT's own UI doesn't show it).

Fix: skip latent spark windows (isLatentWindow: used_percent === 0 and a full-window reset_after_seconds); they reappear once the feature is actually used. The display name now comes from the payload's own limit_name (falling back to the constant), so it tracks whatever OpenAI reports instead of a hardcoded version.

2. Window labels ignored the real window duration

primary_window → "session" / secondary_window → "weekly" were assigned purely by position, never reading limit_window_seconds. On a Pro account whose primary_window is a 7-day window (limit_window_seconds: 604800) with no secondary, the card labeled it "Session".

Fix: the internal session/weekly keys (routing semantics — combo quota scoring, preflight, cooldowns) are unchanged; only the display label is corrected from limit_window_seconds (windowDurationLabel), so a 7-day primary_window shows "Weekly". Genuine 5h windows keep the default label.

Testing

• New tests/unit/codex-usage-quotas-latent-window.test.ts (5 cases): latent spark window omitted; used spark window shown; display name from payload limit_name with constant fallback; 7-day primary labeled "Weekly"; genuine 5h/7d windows keep defaults.
• Existing codex-banked-reset-credits-5199 + codex-usage-quotas-review-window pass (12/12, no regressions). npm run typecheck:core and ESLint clean.

Obrigado, @insoln — mergeado na release/v3.8.49. Validado no tip combinado (merge-train: typecheck + file-size + 106 testes das áreas tocadas + vitest 271/271 verdes). O único red de CI era o base-red compartilhado de complexity (pré-existente na tip da release, não deste PR).
