fix: merge main and pass target input name to asset browser (#8596)

- Merge latest main to resolve conflicts
- Fix asset browser filtering: pass target input name (e.g.,
'ckpt_name') instead of PrimitiveNode's widget name ('value')

**Changes:**
- Add `inputNameForBrowser` param to `createAssetWidget`
- Pass `targetInputName` from `PrimitiveNode._createAssetWidget`
