refactor: Rename list.hbs to listItem.hbs to preserve git history

Isolate the file system rename operation into its own dedicated commit to preserve continuous history tracking within Git. Renaming `list.hbs` to `listItem.hbs` without altering any content ensures Git records this change as a 100% file rename. Decoupling this step prevents Git from misinterpreting subsequent structural template refactors as a destructive file deletion followed by the addition of an entirely new file.

* **Template File Rename (`src/pages/fileBrowser/`):**
* Renamed `src/pages/fileBrowser/list.hbs` to `src/pages/fileBrowser/listItem.hbs` with zero line changes (100% similarity score), guaranteeing clean `git blame` and file history continuity across structural revisions.
