fix: install dinit service packages through netinstall Default group instead of packagechooser

basestrap module (from calamares-extensions) reads netinstallAdd only
for the init provider name (e.g. 'dinit') to add elogind-dinit. It
does NOT install the subgroup packages from the user's packagechooser
selection (networkmanager-dinit, pipewire-dinit, etc.). So these were
selected in the GUI but never present in the target system.

Since the netinstall view's packageOperations -> packages module flow
works correctly, move all required *-dinit service packages into the
netinstall.yaml Default group (online) and profile.yaml rootfs (offline).

Also revert settings.conf back to services-artix + postcfg — these
modules DO exist (from calamares-extensions) and work correctly when
the service packages are installed. Remove the unnecessary shellprocess
files that were added as a mistaken workaround.
