components batch-2: draw CollapsingScaffold + OptionPicker from floret-kit

Agendula now sources the collapsing settings/sub-screen scaffold and the
full-screen single-select picker (FullScreenPicker/OptionPicker) from the kit's
components module. Deletes the app copies; repoints SettingsScreen imports and
adds the FullScreenPicker import in ReminderLeadPicker. Submodule re-pinned.
ReminderFormatting stays app-local (needs a label-callback API — separate pass).

Clean composite build + tests + lintDebug + debug assemble green.
