File download are just ported legacy code, might want to fix it

Also context menu aren't properly showing it on home screen

Removed the fallback clipboard copy code since it looks like the whole project is targeting es2022.

Also cleanup/restructure some i18n strings

…ri app

Added the following packages:
- tauri-apps/api
- tauri_plugin_upload (handle stream download)

Both clipboard and file download should now use their respective native API.
Clipboard use either the navigator or tauri clipboard API
File download use the <a> download trick or use the downloader from tauri_plugin_upload
since using stream download would be better so it does not eat memory.

Added a new task to handle file download announcement (Tauri only)
Maybe add a way to announce error to the task manager.
Also cleaned up old legacy code for file download.

…ve Tauri API for Tauri app"

This half reverts commit 6c706cd.

Only remove the Tauri part since it would be better to make separate PR for it.

Also did some refactoring

More inline with jf-web since they did not include it

Instead of manually using item check, this works much better and consistently.
Just need to add the item fields to relevant request.

The following context menu has been adjusted for multiple media streams:
- Delete (should correctly delete the selected stream)
- Identify (should correctly applied to selected stream)
- Media Info (should show ONLY the selected stream)
- Metadata editor (should correctly show/edit the selected stream)

The multi-supported context menu would only show on the following:
- Item page
- Playback bar (audio mode)

If a multiple streams got selected outside the item page, it will show the first stream information only. (with the exception of Media info)
