fix(data): fix queries and thresholds across multiple exporters

Browse source 
- Ceph: fix OSD latency metric name (ceph_osd_apply_latency_ms), replace
  ceph_osd_utilization with ceph_health_detail{name="OSD_NEARFULL"}, add for: durations
- ZFS: improve description, remove incorrect ON() join on readonly check
- Thanos: filter gRPC errors to actual error codes only (drop NotFound, Cancelled, etc.)
- Loki/Promtail: fix histogram_quantile to aggregate by (namespace, job, route, le)
- Mimir: raise rate()>0 thresholds to >0.05, add missing for: durations
- OTel Collector: raise rate()>0 thresholds to >0.05, add deprecation comments
- Tempo/Cortex: raise >0 thresholds to avoid transient spikes
- APC UPS: add division-by-zero guard on battery voltage ratio
- DigitalOcean: raise increase()>0 to >3
- Grafana Alloy: fix missing name: field on exporter

This rule fires on any non-OK state. Split into separate warning/critical rules by using ==1 and ==2 thresholds if needed. The official Ceph mixin splits this into separate warning (==1) and critical (==2) alerts.
This rule fires on any non-OK state. Adjust severity or split as needed.

Ceph internally triggers OSD_NEARFULL based on the nearfull_ratio (default 85%). Ceph internally triggers OSD_NEARFULL based on the nearfull_ratio (default 85%).
ceph_health_detail can also be used for more granular OSD space alerts. The official mixin uses ceph_health_detail for OSD space alerts.
