**Related issue:** Resolves#46965
Relative "time ago" timestamps switched to months at ~30 days, so a
timestamp 45 days ago read "about 2 months ago" (even 89 days showed "3
months ago"). This centralizes the day/month cutoff in a new `timeAgo`
helper and routes existing call sites through it, so anything under 90
days is shown in days.

## Summary by CodeRabbit
* **Bug Fixes**
* Relative “time ago” timestamps now keep values in **days** for items
under **90 days**, switching to **months** later for more accurate
wording.
* Improved consistency of relative time labels across status modals,
activity feeds, host details, and management screens (including “last
updated,” “uploaded,” and “added” text).
* **Tests**
* Added/updated coverage for the shared relative-time cutoff and
formatting behavior to prevent regressions.
