feat: execute the antergos-minimal profile (PLEASE SOMEONE HIRE ME)

why did i make a second whole ISO profile nobody asked for. a
standalone Xfce "lightweight" edition i never tested, never updated,
and that ONLY depends on orphaned packages i forgot existed
(calamares-branding-antergos-next-minimal, antergos-xfce-theme —
both still buildable, now completely dead weight, because the only
thing that referenced them was this file).

the real lowest of it is: it was the "offline calamares installer."
you know what that does now? tries to unpack a squashfs that NO live
profile builds anymore. it points a loaded gun at my foot every day
and today i finally squeezed. its last commit was renaming a theme
and telling a bot to shut up about pkexec. thats where we ended up.

it was never tested. it was a ghost. so i killed it.

actual changes:
- RIP iso-profiles/antergos-minimal, all 95 files of it (good
  riddance, you were a lie)
- hauled 7 orphaned live module configs (initcpio/locale/mount/
  partition/umount/users/welcome) out of the wreckage into the main
  calamares/modules/ where they always lived — git LIED and called
  them "renames from minimal" because the copies were byte-identical.
  they were never from minimal. git is a LIAR.
- users.conf: cut the libpwquality crutch so 4-digit PINs stop getting
  called weak. i built a pin picker. let it. breathe.
- netinstall (both variants): +vulkan-nouveau so NVK covers Turing+
  without dragging in nvidia-open
- antergos-xfce-theme + calamares-branding-antergos-next-minimal:
  now truly, blessedly orphaned.

the profile is dead. long live the profile. i am NOT maintaining two
ISOs in this economy.
