Subject: [PATCH] C2(deploy-infra-alerting): impl fix TextfileStale to always
 return data
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Query all textfile mtimes (time() - node_textfile_mtime_seconds) and
threshold at > 3600s, instead of filtering with > 3600 which returns
empty results when everything is fresh.

This means:
- Fresh textfiles: query returns low values, threshold not met → OK
- Stale textfiles: query returns high values, threshold met → Alerting
- Missing textfiles: series vanishes, noDataState=Alerting → Alerting
