Subject: [PATCH] fix: change HTTP status code from 400 to 502 when no provider
 available

Fixes #1082

When all Antigravity accounts are unavailable, the error response now returns
HTTP 502 (Bad Gateway) instead of HTTP 400 (Bad Request). This ensures that
NewAPI and other clients will retry the request on a different channel,
improving overall reliability.
