perf(l2): heavy screens build in pieces over several loop passes

Browse Source 
The list fill becomes a small job queue (fill/then/fillStart, fillTick with a
25 ms budget per pass). Settings pages build section by section in
schemaRows, with the trailing extras (melodies, prune, quick messages) queued
after them so the order stays; Radio and Repeater build by group, Admin's
repeater pick like the contact list, Diag's Live tab by section. Rebuilds
that restore the scroll flush the queue first. Screens went from 220-360 ms
to 80-175 ms (build + first frame).

Diag's crash line read the core dump in flash every second (~44 ms each);
it is read once now. The perf run times every page and dismisses the USB
popup, which had covered all earlier measurements.
