feat(edit): add a searchable time-zone picker (#31)

Surface the zone as an optional form field, right after the time fields
it qualifies: hidden on ordinary events, revealed automatically when the
event already carries a foreign zone, and withheld entirely while all-day
is on (a date-anchored event has no zone to show).

The picker is a full-screen one per the app's convention, but it can't
reuse OptionPicker: that composes every option eagerly, and ~600 zones
would all compose on open. It drives its own LazyColumn instead, which
needs the kit's new `scrollable = false` — the scaffold's own
verticalScroll would otherwise throw on a nested same-axis scrollable.
The device zone and recently-picked zones pin to the top so the common
case needs no typing; search is accent- and case-insensitive.

Recents persist in DataStore, capped at five, dropping ids the tz
database no longer knows.
