Summary

Add unpartitioned free space detection as alternative to shrinking a partition
Fix double /dev/ prefix bug in collect_partitions (lsblk -p returns full path for PKNAME)
Fix btrfs resize: use online resize instead of unmount (avoids busy-partition failures on mounted filesystems)
Replace parted resizepart with sfdisk --no-reread --force to avoid interactive TTY requirement
Set GPT partition name to anacondainstall for the new OEMDRV partition
Fix early non-root exit (script now exits immediately before any other code)
Update install.md: document download-then-run approach since process substitution does not survive sudo

Test plan

Tested end-to-end on a VirtualBox VM via SSH: btrfs online shrink + sfdisk resize + parted mkpart + mkfs.btrfs + mount + git clone all succeeded
Non-root early exit verified
Free space detection path covered by collect_free_space / show_free_table

Fix Nextcloud app password not stored in KWallet after autoprovisioning 576363cdca

The Flatpak autoprovisioning command does not reliably write credentials
to KWallet from inside the sandbox. After provisioning, directly write
both KWallet entries (user:url/:0 and user_app-password:url/:0) via
qdbus, creating the Nextcloud folder first if needed. kwallet-query was
tried but silently returns 0 without creating missing folders.

Add install.sh bootstrap script to create OEMDRV partition 5d0c674bec

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.

Add free space detection to install.sh as alternative to partition shrinking 9e16162077

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

Fix double /dev/ prefix bug in collect_partitions bfa5515d75

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

Fix btrfs resize: use online resize instead of unmount/remount bf71540f66

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.

Fix parted failing on busy partition in script mode 5c2182a1c9

parted -s answers confirmation prompts with "no" (conservative),
causing resizepart/mkpart to fail on a mounted partition. Pipe
"Yes" to parted stdin instead so busy-partition warnings are
confirmed and the operation proceeds.

Replace parted resizepart with sfdisk --force 5ef48c84e5

parted fails to resize a mounted partition non-interactively.
sfdisk --no-reread --force writes the updated partition table
directly without TTY/confirmation issues, and partprobe
re-reads it afterwards.

Update install.md: download script before running with sudo 1f17ef5c2f

Process substitution does not survive sudo, so the script must be
downloaded to a temp file first.
