The desktop window always reset to its default size after restart
because no WindowState was persisted. Add WindowStateStorage backed
by multiplatform-settings (java.util.prefs on desktop) to save and
restore width, height, and position. Use snapshotFlow inside the
Window composition to persist changes continuously, with an explicit
Preferences.flush() to ensure values reach disk before exit.
Also add 'desktop-install' Makefile target to rebuild and copy the
app to /Applications/myicek.app.
Replace per-player cards with a single card listing all players. Each
player shows on one line: number, name, position, and birth year in
muted color. Add Makefile with android and desktop targets.
