- Add betterframe-expand-data systemd service: growpart + resize2fs on BF_DATA (last partition) so it fills the full SD card on first boot. Solves the "No space left on device" issue with OS update downloads. - Change OS update staging dir from /var/tmp/betterframe to /var/lib/betterframe/tmp (on BF_DATA partition, not rootfs). - Wire firmware and OS update progress callbacks into the GTK overlay banner — shows "OS Update v1.2.3: Downloading — 45%" etc. - Add per-partition disk reporting in heartbeat (/, /boot/firmware, /var/lib/betterframe) with total/used/free/percent. - Display partition table on kiosk detail page in admin UI. - PG + SQLite migrations for partitions_json column on kiosks.
