Break down the monolithic FolderPickerModal component into smaller, highly cohesive modules to improve maintainability and separate concerns.
- Extract UI sub-components into dedicated files (`FolderRow`, `StagedFoldersPanel`, and `StatusLine`).
- Move path manipulation, string formatting, and breadcrumb utilities into a dedicated `pathUtils.ts` file.
- Abstract complex local state, API calls, and event listeners into a custom `useFolderPicker` hook.
- Clean up `FolderPickerModal` to act as a lightweight presentation layer.
