[bugfix] Asset widget search matches display label (#9774)

## Summary
Asset widget dropdown search only matched against `item.name`
(filename), but users see `item.label` (display name). Now searches both
fields so filtering matches what is visually displayed.

## Changes
- **What**: `defaultSearcher` in `FormDropdown` now matches against both
`name` and `label` fields
- Added 3 unit tests covering label-based search scenarios

## Review Focus
- The change only affects cloud asset mode where `name` (filename) and
`label` (display name) differ. In local mode, `label` is either
`undefined` or identical to `name`, so behavior is unchanged.
