fix(plant): review-gate fixes — level-based UPS re-polls, test hardening [#790 #344]

Adversarial review verdict FAIL -> addressed: runtime-low + shutdown
chain re-poll /5 min (edge-crossing could miss a page mid-outage);
suppression stamp set after notify; plan body names all 7 hosts
explicitly; test fixes (pipefail SIGPIPE, comment-only assertion).
Reviewer P1 'tripp_lite slug' refuted with live entity registry
evidence (entity_id derives from name; sensor exists, 8f48730 aligned).
On-box ha core check passed with the changed files.

Review thread: #3
