Subject: [PATCH] Add UTC timestamp tooltip to Last Check time

Shows the full UTC timestamp when hovering over the relative 'time ago'
text on the equipment detail page.

Changes:
- Wrapped time_ago display in a span with title attribute
- Title shows full datetime in UTC format
- Added cursor-help class for visual hint that tooltip is available

Users can now see both the easy-to-read relative time ('5m ago') and
the precise UTC timestamp (2026-01-04 19:30:15Z) by hovering.
