fix(run-history): human-readable Triggered column + insights header

The Triggered column was rendering the raw ISO timestamp straight
from the API, which is hard to read at a glance. Now the cell shows a
locale-formatted date ("Oct 14, 2026, 3:25 PM") with a muted relative
time below ("2h ago" / "in 3h"); the full ISO sits in a native
tooltip for machine-precise inspection. The expanded insights panel's
header reuses the same formatting.
