fix(lsposed): show user-app hidden count in save snackbar (#88)

The post-save snackbar was reading hiddenPkgs.size, but hiddenPkgs has
selfPkg appended unconditionally (so the kernel-side list always
contains vpnhide itself), so the displayed count was always one higher
than what the user actually selected.

Switch to the same hiddenCount/observerCount values the screen header
already uses (allApps.count { it.hidden / it.observer }) so both
counters stay in sync and don't drift if the hiddenPkgs assembly logic
changes again.

Closes #79.
