feat(components): let picker content own its scrolling

CollapsingScaffold always wrapped its content in a verticalScroll Column,
which composes every row up front. That suits the short lists these
surfaces normally hold, but it rules out a LazyColumn entirely: nesting a
same-axis scrollable inside it throws, so a caller with a few hundred
options had no way to render them.

Add `scrollable` (default true, so every existing caller is unchanged).
When false the content gets a plain column to fill and brings its own
scrolling container, keeping the insets, IME padding and top-bar collapse
as they were. FullScreenPicker forwards the flag for pickers that need it.
