- edit_volume passed driver_type to attach_disk, which has no such parameter, so every bus change failed after the disk was detached; pass format_type. - A disk without a driver type shows "None" in the edit form; keep the disk's current format instead of rejecting it. - Validate with fullmatch, so a trailing newline is no longer accepted, and use one volume-name pattern for disk views and clone.

Regression tests for ROADMAP Wave 0 item 1 (S-02, S-03, S-04):

disk and media mutation views must be superuser-only (matching the UI, where

the Disk tab is only rendered for superusers), and even for superusers the

views must not act on volumes or option values taken blindly from the client.
