Make the transfer loop feel live: parse real core progress payloads, show
progress on send/receive surfaces, allow cancel/stop, retry failed receives,
and fix delivery-phase events so receiver completion updates the UI.
Default Android receive destination is now the shared system Downloads
collection (like desktop), using MediaStore on API 29+ instead of
app-private storage. Legacy app-private defaults are promoted back to
public Downloads so existing installs pick up the fix.
Tighten cold-open and in-app invitation handling so ticket acquisition is
stricter and less racey across hosts, and expand automated coverage for the
receive history and acquisition flow before merge.
Refactored SettingsScreen to display device information and allow user to choose between System, Light, and Dark themes. Updated AppUiState to remove unused diagnostics visibility flag.
