Allow removing multiple LXC mountpoints

Update `remove_lxc_mountpoint` in `storage-share-helper.sh` to support multi-select mountpoint removal for a container. Each selected mountpoint is now confirmed individually (default No), processed independently, and reported in a final result summary with `removed`, `FAILED`, or `skipped` status.
