Fix downloads and investigate UX issues

[PintoGideon]

The current implementation of browser-triggered downloads in our file browser feature requires improvements to enhance user experience and functionality. This issue focuses on refining the download process initiated directly from the browser within the file browser interface.

Features to Implement or Enhance:

• Download Confirmation: Implement a download confirmation dialog to inform users that the download was successful
• Download Progress Indicator: Introduce a download progress indicator to provide users with real-time feedback on the download status. This will now be handled implicitly by the browser
• Download Error Handling: Enhance error handling mechanisms to gracefully handle download failures, network interruptions, or server errors, providing users with clear error messages and instructions.
• File Metadata Display: Display relevant file metadata (e.g., file size, file type) alongside the download link to help users make informed decisions before initiating downloads.
