Add temp target display to live activity lock screen widget

When a temp target is active, an orange badge showing the temp target
name appears in the top-trailing corner of the chart overlay — mirroring
the existing purple override badge. Both badges stack vertically if an
override and a temp target are simultaneously active.

Pipeline mirrors the override pattern end-to-end:
TempTargetData struct → fetchAndMapTempTarget() in DataManager →
@Published tempTarget in LiveActivityData → TempTargetStored Core Data
observer in LiveActivityManager → five new fields in ContentAdditionalState
→ orange badge in LiveActivityView.
