tommy 38fa22d444 monitoring: add quarterly UPS self-test script (Phase 4B) ...

ups-quarterly-test.sh:
  - Runs test.battery.start.quick on cyberpower1 then cyberpower2
  - 120s wait between tests (allow recharge)
  - Logs pass/fail to syslog via logger -t ups-quarterly-test
  - Password stored in single-quoted variable to prevent shell expansion
  - Deployed on beast (/usr/local/bin/), cron: first Sunday of Jan/Apr/Jul/Oct 02:00

Manual run 2026-05-06:
  cyberpower1: Done and passed (charge 97% post-test, recharged normally)
  cyberpower2: Done and passed (charge 100%)

Grafana alerts (in grafana.db):
  cfl8lrs1mxnnka  UPS Battery Charge Low (<80%) — break-tested pending ✓
  afl8lrs4mbaioa  UPS On Battery (power outage) — break-tested fired ✓

Note: nut_battery_test_result not exposed by nut-exporter v1.2.1.
Pass/fail tracked via syslog only for now. Adding to Phase 5 if exporter
gains test-result metric support.
