Live activity loop staleness indicator does not always reflect actual loop status #2393
Description
Describe the bug
The loop staleness indicator in the live activity does not always update when the live activity is updated, resulting in a mismatch between the status displayed in the live activity versus in the Loop app.
It seems as if the indicator is not re-rendered with every update of the live activity.

To Reproduce
I'll be honest, I don't have consistent reproduction steps. Sometimes I observe the loop staleness indicator showing a "warning" status. Then I open the Loop app to see what's happening but observe that the loop staleness is actually "fresh". I don't know what the trigger is. See screenshots below for an example.
Expected behavior
The Loop staleness indicator should correctly update whenever the live activity is updated, such that the staleness indicator always reflects the current loop status.
Screenshots
This screenshot was taken on the lockscreen, before opening the Loop app. Note that the live activity was updated at 13:45 and it is currently 13:46 (both times in UTC+1)
From the attached Loop report we see that in the StatusExtensionDataManager section, it lists "lastLoopCompleted": 2026-01-14 12:45:08 +0000 so the loop is "fresh". So at 13:46 (UTC+1) the live activity should display the "fresh" status. However, the live activity displays the "warning" status in the loop staleness indicator instead and has last updated at 13:45.
As an aside: I don't know why the first few hours in the live activity are empty. This may be a separate issue?
Directly after this, I open the app, the Loop staleness indicator indicates the Loop is fresh.
If I go back to the notification center immediately afterwards, the live activity was updated at 13:46 and the Loop staleness indicator is correctly updated to display the "fresh" status.
