The stale-pending cleanup task previously hardcoded status_code=504 and a
generic timeout message for every usage row it finalized. When a request
had already been observed as failing — e.g. upstream Connection reset by
peer, watchdog 504, or an authenticated 4xx — the cleanup overwrote that
context with a misleading "服务器超时" outcome and 504 status, hiding the
real cause from the dashboards and customer.
Pull the most recent failed/cancelled candidate per stale request_id and,
if present, finalize the usage row with the candidate's status_code
(defaulting to 502 when none was recorded) and error_message. Requests
that have no terminal candidate (truly stuck pending/streaming) keep the
existing 504 + timeout-message behavior, since they really are timeouts
from the cleanup's perspective. Applied to all three SQL backends with
parameterized UPDATE statements.
The Postgres failed-candidate lookup orders by
COALESCE(finished_at, started_at, created_at) DESC, matching the MySQL
and SQLite ORDER BY clauses so the three backends pick the same
"most recent terminal candidate" under every NULL combination of timing
columns.
