v0.128.1: suppress the class hint on USB drives (ruling F5)

Only Observe-sourced drives ever carried class, so legacy PVE dir:-backed USB
drives showed 'lassú' while registry-sourced ones never did. The card already
carries the USB type tag. Hub-report ClassHint UNCHANGED (UI-only). Pinned by
TestStorageTemplate_USBClassBadgeSuppressed (red-proof run).

 ## Changelog
 
+### v0.128.1 — USB drives never show the rotational class hint (2026-07-13, ruling F5)
+
+`storage.html` `classTag(d)`: `if(d.type==='usb') return '';` ahead of the class branches —
+covers both render sites (card badges + metarow, the latter already guards on `d.class`).
+Rationale: only Observe-sourced drives ever carried `class`, so the demo's legacy PVE
+`dir:`-backed USB drives showed "lassú" while registry-sourced drives never did — a misleading
+inconsistency, and the card already carries the USB type tag. Non-USB storages (e.g. a future
+internal SATA data drive) keep the hint. **The hub-report `ClassHint` field is UNCHANGED**
+(documented hint; UI-only suppression). Pinned by `TestStorageTemplate_USBClassBadgeSuppressed`
+(red-proof: guard removed → FAIL "classTag USB guard missing"). Part 1 of the demo
+storage-hygiene task (Part 2 = host-side `pvesm remove` of the two legacy dir storages —
+operational, no repo change). Task was numbered v0.127.3 pre-sequencing; ships as v0.128.1
+(0.127.3 + 0.128.0 already taken).

 The Restore/import flow no longer requires copying `.fab` files to `{tároló}/exports/` by hand
