Anonymous Docker volumes carry a raw 64-character hex name, which is correct
data but unreadable in the volume browser crumb, sheet title, and table row.
Detect 64-hex names and show a short prefix (e.g. 079dfda49f2c…) in the table
cell and sheet title, with the full name available on hover and an "anonymous"
chip so the truncation is self-explanatory. The volume browser sheet adds a
band that keeps the full hash visible and copyable. Named volumes still display
in full. The name is passed verbatim to the API; only the rendered label changes.
