* Studio: make the model download folder reachable from the Hub, and findable in search
The only control for where models download lived in Settings > System >
Storage, labelled "Model downloads". Settings search matched a row's visible
label only, so "models folder", "directory", "path" and "drive" all returned
nothing, and users concluded the location could not be changed at all.
Hub > On-device locations now leads with a Download location row: current
path, Change (folder browser on web, native picker on desktop), Use default,
free space, and a note when HF_HOME pins it. That dialog is where people
already look for where models live, but it only managed read-only scan
folders. Changing the location refreshes the inventory.
Settings search now also matches per-row keyword aliases, so "folder",
"directory", "path", "location", "drive", "disk" and "cache" find the row.
Relabels it "Models folder" and says it can be moved off the system drive.
Adds the German strings for the block, which fell back to English.
* Re-read the download location on every open, and drop it when the read fails
The dialog stays mounted between opens, so a reopen that hit a failing or slow
GET /api/settings/hugging-face-cache kept showing the previous path with Change
and Use default still enabled, as though it had just been confirmed.
The loaded flag is re-armed on each open and a failed read now clears the
settings, so the field falls back to Unknown and both buttons disable until a
read succeeds.
* Let the inventory version bump be the only refresh after a cache move
updateHuggingFaceCacheSettings already bumps the inventory version, which
re-fetches every source. Calling onInventoryChange as well started a second
round under the previous version, and the differing keys meant the two could not
be deduplicated, so moving the folder scanned everything twice.
The settings Resources tab already relies on the bump alone for the same call.
