Promote the richer variants Calendula had kept app-local into the shared kit, as
backward-compatible additions (every new parameter defaults to the prior
behaviour, so Agendula's call sites are unchanged):
- GroupedRow: add `dimmed` (fade headline/summary to M3 disabled emphasis while
the trailing control stays live — for present-but-off rows) and `container`
(tonal-colour override, e.g. a category tint).
- CollapsingScaffold: add `actions` (trailing app-bar items), `snackbarHost`,
and opt-in `predictiveBack` (wires the back-gesture preview to onBack for
full-screen surfaces that want it).
- FullScreenPicker: thread opt-in `predictiveBack` to the scaffold, and apply
SOFT_INPUT_ADJUST_NOTHING so a picker's own imePadding lifts the focused field
instead of leaving a black gap above the keyboard.
- OptionPicker: forward `predictiveBack` and add an optional `header` slot above
the option rows.
