refactor(ui): one selection check and one motion spec across the pickers

Three inconsistencies the recurrence-picker review surfaced, all of the
same kind: the redesigned picker had quietly diverged from the family.

SelectedCheck existed as five copies app-side plus a private one in the
kit, and they had drifted — the kit drew Icons.Rounded.Check, every app
copy drew Icons.Default.Check. Delete all five against the kit's now
public primitive (floret-kit!2), which settles the glyph on Rounded.

The recurrence picker was the only full-screen picker whose selected row
carried no check, relying on the tonal highlight alone. Add it to all six
rows, matching OptionPicker, reminder, agenda range, timezone, calendar
and Settings.

Its two new AnimatedVisibility blocks were the only ones in the app using
Compose's bare defaults rather than expandEnter()/collapseExit(). Those
helpers honour rememberReduceMotion(), so the weekday and count cards
were ignoring the system "remove animations" setting — an accessibility
regression, not just a style drift.

Bumps the floret-kit pointer; needs floret-kit!2 merged first.
