btrfs supports live filesystem resize, so there is no need to
unmount a mounted btrfs partition before shrinking it. This also
avoids umount failures when the partition is busy (e.g. /home with
an active SSH session). ext4 still requires offline resize.

lsblk -p returns PKNAME as a full path (/dev/sda), so stripping
the basename before prepending /dev/ avoids /dev//dev/sda.

If a disk has unpartitioned space >= 4096 MiB, it is offered as a direct
target for the OEMDRV partition, avoiding any filesystem resize.

Shrinks a selected ext4/btrfs partition by 4 GiB, creates a new BTRFS
partition labeled OEMDRV, mounts it to /opt/sys_config and clones the
repository into it.
