Fix settings i18n parity coverage

 - **PR #2165** by @starship-s — Pooled OpenAI Codex quota status surfaced in the Providers panel. Pre-fix, the Providers page presented Codex quota as if there were only one credential/account state, which was misleading when users authenticate through a credential pool with several usable credentials, temporarily exhausted credentials, failed probes, and different reset windows. Now the active provider quota card includes a credential-pool summary (available / exhausted / failed / checked counts), displays the best currently-available pool windows in the collapsed view as "Best of N", and exposes per-credential detail behind an expandable section. Exhausted credentials are intentionally NOT re-probed while their cooldown is active (matches credential-pool selection behavior, avoids generating failed quota calls from a status page). Manual refresh still means "probe now" but transient refresh failures preserve the last known-good snapshot. JWT decode (`_decode_jwt_claims_unverified`) is used only for token-shape classification (Codex OAuth JWT vs raw OpenAI API key), explicitly NOT for authorization — documented in the function docstring. Per-row plan labels only shown when verified account-limit data is available. Concurrent probing capped at `min(_CODEX_POOL_MAX_WORKERS=6, len(probe_items))` so page render time stays bounded on large pools. Transient `None` probe results are NOT cached (only known unavailable/exhausted states are cached); 32-test regression suite covering pool snapshot, concurrent probe, JWT detection, cache invalidation, transient-vs-known cache distinction, and i18n parity across all currently-supported locales. Scoped to OpenAI Codex (the only provider with the credential-pool/account-limit path needed to surface this accurately).

+- Settings i18n parity now covers every `settings_label_*` and `settings_desc_*` key referenced by `static/index.html`. Adds the missing Italian and French translations for the Fade text effect preference and cleans up existing settings-key parity drift in Portuguese and Traditional Chinese locale blocks.
