fix: include cause in failEnvironmentCloudInternalError log output

The structured cause was passed to EnvironmentHttpInternalServerError but
omitted from the Effect.logError call, so relay and secret-store failures
lost the full cause chain in server logs (the HTTP response schema only
serializes _tag and message, not cause). Re-add { cause } to the log call
to match the pattern used by failEnvironmentInternal in auth/http.ts.
