New paging engine, backhaul alerting, power devices

The paging engine was rebuilt end to end (severities, per-timespan rules, PagerDuty support, rate limits), and backhauls and power devices now have their own metrics and alerting.

Paging engine rebuilt New

A ground-up rebuild of paging: issue severities, per-timespan rules per user and delivery method, PagerDuty support alongside SMS and email, rate limiting, and repage limits. The issues list gained severity icons, sortable dates, and human-readable durations. Legacy paging is deprecated.

Backhaul metrics and alerting New

Backhauls are now monitored in their own right: capacity and usage metrics with thresholds, collapsible threshold menus, and default paging rules on every backhaul.

Power device monitoring New

Ubiquiti power managers join the map as a device class: battery graphing, state of charge, DC power draw, and backup-radio status on Wave and GigaBeam radios — so you can watch a tower ride out an outage on batteries.
