vm create wizard: block volume added in Storage step is silently dropped, not created

[nghia-su]

• Steps to reproduce: verda vm create → interactive wizard → Spot/CPU/etc → at Storage step choose "Add new block volume", set name/size → when prompted again, choose "None (skip)" → confirm deploy.
• Expected: the block volume should be created and attached, appear in the deployment summary and in verda volume list.
• Actual: volume is missing from the summary, from the VM's storage list, and from verda volume list

Thanks for the detailed report — the reproduction steps made this easy to pin down.

Confirmed: it's a real bug in the storage step of the vm create wizard. Queued volumes are held in local step state and only flushed when you pick Done, but the menu kept showing None (skip) at row 0 after you added a volume (right where the cursor rests) — hitting it silently discarded the queued volume instead of keeping it. Nothing was created, which is why the summary and verda volume list came up empty.

Fix is up in #56: None (skip) is now only offered on the fresh storage menu; once volumes are queued the choices are add-more/Done, and Esc still backs out. Regression tests included.

Thanks again for taking the time to write it up!
