kshitijk4poor 5e2d55ca9c fix(codex): quota probe and /usage pool paths use the pool route base
Pool rows keep the canonical chatgpt.com URL, so the quota-restored probe
(auth_codex + CredentialPool) and the /usage tier-3 and forced-refresh
paths paired a gateway key with chatgpt.com/backend-api/wham/usage. Route
them through _codex_pool_route_base_url, the chat route's rule
(HERMES_CODEX_BASE_URL > model.base_url > row URL).
