fix(ci): apply the pending release-pipeline review fixes

Restores the ALSA layout binds in both snap recipes (bit-perfect hw:
access inside the snap), lets the build cache save on main as well as
slint-mvp, installs the desktop file as com.blitzfc.qbz.desktop so the
AppStream launchable and the MPRIS DesktopEntry resolve in deb/rpm,
clears the stale boot-restore error when a new browser sign-in starts,
and adds the X11 dlopen libraries to the flake's runtime set. The
flake version/rev/srcHash bump remains a tag-time step (documented in
the release checklist, which is rewritten for the 2.0 Slint flow).
