Refactored helpers to reduce duplication and improve naming.

- Renamed chroot_install/chroot_enable to chroot_pacman_install/chroot_systemd_enable.
- Made chroot_systemd_enable auto-print status, removing need for wrapper functions.
- Used generic prompt helpers instead of duplicating logic in specialized functions.
- Inlined and removed single-use wrapper functions throughout.
