refactor: remove any types from fuseUtil, ui, isobmff, and fix clipspace

- fuseUtil.ts: Changed isFuseSearchable type guard from any to unknown with proper null checks
- ui.ts: Changed Props index signature from any to unknown
- isobmff.ts: Changed extractJson return type from any to unknown with type assertion at call site
- clipspace.ts: Fixed pre-existing typecheck error by changing createImgSettings and createImgPreview to return null instead of empty array
