Re-shoot the phone screenshots, and fix what taking them exposed

The phone set was two days old and predated M16-M20: nothing in it showed the copy-to picker, the
trash's window or the compress dialog. It is now eight shots (Play's maximum) taken from the signed
release build over the demo library: home, folder list, photo grid, storage usage, sort sheet,
Copy to..., the trash with its 24-hour line and Empty trash, and the compress dialog with its switch.

The shots have to stay inside the demo library, so two things were deliberately not captured: the
home screen (its library counts are the real phone's - the old AVD-shot file is kept) and the picker
one level down (it would name real folders). The picker is shot at the volume list instead.

Taking the picker shot exposed a real bug: it listed '.plainfiles-trash' among the destinations,
because unlike every other listing it did not filter hidden entries. Hidden folders are now offered
only when the listing shows hidden files, with a test for both halves.

The tablet sets are unchanged. The tablet AVDs cannot boot on this machine (no KVM) and the
phone-resized path needs more navigation work than this session had left; the checklist says so and
records what to regenerate and where.
