Add download indicator and progress for files

[IgorShadurin]

Description Currently, Fairdrive does not provide any visual indication or progress information when a file is being downloaded. This can lead to confusion for users who may not be sure if the download is in progress or if it has stalled. To improve the user experience, it would be beneficial to show an indicator that a download is in progress and, ideally, display the download progress as well.

Proposed Features Show a visual indicator (e.g., spinner, loading bar) when a file download is in progress. Display the download progress as a percentage or progress bar, so users can track the status of their downloads.

@IgorShadurin Do you have any suggestion where to place these progress bars?

Users can download files from the three dots menu in the file list and from the preview side bar.
