v2.6.0

Added

• IMAGE_STORAGE config variable: the storage pool where the Alpine .tar.xz template image is downloaded. Prompted during template creation (step 3b) with the list filtered to pools that have the vztmpl content type enabled. Saved to ~/.proxmox-lab.conf and pre-populated on subsequent runs. Defaults to local when not set, preserving existing behavior for users upgrading.

Fixed

• Template creation no longer hardcodes local for the Alpine image download (pveam download), existence check (pveam list), or container creation (pct create … local:vztmpl/…). All three now use the configured IMAGE_STORAGE.
• System cleanup (_cleanup) now discovers Alpine images via pveam list <IMAGE_STORAGE> instead of scanning /var/lib/vz/template/cache/ directly, and removes them via pveam remove instead of rm -f. This correctly handles non-local image storage pools.
• Summary display during template creation now shows CT Disk Storage and Image Storage as separate labeled fields.
