v0.79.0: disk view keys the "registered" check on the stable path

Follow-up to v0.78.0. The disk-view JS (settings.html regBadge/actions) checked
registration by the raw mount_path, but the registry stores the stable path since
v0.78.0 — so enrolled drives showed a spurious "Nem regisztrált" badge + Register
button. Fix: regKey(d) = d.guest_path || d.mount_path (agent reports the stable
guest_path per disk); registerDrive still posts the raw path. Display-only.

 ## Changelog
 
+### v0.79.0 — disk view: key the "registered" check on the stable path (2026-06-23)
+- Follow-up to v0.78.0. The storage disk-view JS (`settings.html` `regBadge`/`actions`) decided whether
+  a drive was registered by looking up its **raw** `mount_path` (`/mnt/<name>`) in the registry — but
+  since v0.78.0 the registry correctly stores the **stable** path (`/mnt/felhom-drives/<name>`), so an
+  enrolled, working drive showed a spurious **"Nem regisztrált"** badge + **"Regisztrálás"** button.
+- Fix: new `regKey(d)` = `d.guest_path || d.mount_path` (the agent already reports the stable
+  `guest_path` per disk); `regBadge`/`actions` now key on it. `registerDrive()` still posts the RAW
+  `mount_path` (the agent operates on raw; `handleStorageRegister` maps it to stable). Display-only.

 ### v0.78.0 — storage register: use the STABLE intermediary path, not the raw path (2026-06-23)
 - **Bug:** `handleStorageRegister` (the "Regisztrálás" action for an already-mounted, unregistered drive)
   registered the **raw** `/mnt/<name>` host path verbatim, unlike its siblings `runStorageInit`/
