app: insets on the two newer screens, and one source for the run count

On-device verification found both.

safeDrawingPadding() was on the run screen but not on Settings or History -
they were added later and never got it - so "< Back  Settings" sat under the
status-bar clock. The same fault the run screen had already fixed, reintroduced
by new code that did not know about it.

Settings also read "0 run(s), 23 kB stored": the count came from
UiState.history, which stays empty until the History screen has been opened,
while the size read the archive directly. Two sources for one fact; the count
now reads the archive too.

Verified on a OnePlus 15 (A16): header clears the status bar, count reads
"1 run(s), 23 kB stored".
