Subject: [PATCH] feat(filepicker): add file selection persistence

- Introduced `FileSelected` field to `Model` to store the selected file name.
- Updated `Update` method to restore the selected file index based on `FileSelected`.
- Adjusted min and max values to ensure the selected file is within the visible range.
