<fix>[storage,localstorage]: backport ZSTAC-85572/85581 to 4.8.38

[MatheMatrix]

Backport to 4.8.38 — cross-repo group @@3 (zstack-utility + zstack + premium, must merge together)

Cherry-picked from 5.5.x:

• ZSTAC-85572 f70f6403bb <fix>[storage]: update reference after mark snapshot as volume — double-nfs vm restart fail (import-order conflict resolved)
• ZSTAC-85581 eb1c5fd057 <fix>[localstorage]: set diskoffering uuid on LocalStorageDesignatedAllocateCapacityFlow — core half of root-volume qos fix

⚠️ ZSTAC-85581 spans core + premium — must merge together with the premium @@3 MR (a827e9d02c adapted).

Full premium build green locally. Cases run by CI.
