fix(codex-bridge): remaining audit findings (routing, trimming, retries, model list fallback, logging)

Second batch from the ten read-only audits; 126 bridge tests. Among them: a spoken number
("opus beş beş") resolves, a used route no longer expires after 7 days, the local reply says how to
go back, an unrouted 9r/ name gets a local 503 instead of going to chatgpt.com, a combo request is not
resent after the upstream closed it, the last model list is served when chatgpt.com is unreachable,
trimming keeps the real last user message, Claude-member combos use the Claude estimate, CRLF SSE is
handled, log lines carry the date and the status endpoint reports a code fingerprint.
