follow-up to files_trashbin to vue migration

[szaimen]

Follow-ups to #36534

Bugfixes:

• Improve loading indicator for actions
• Breadcrumbs show Foldername.dTIMESTAMP when browsing a deleted folder, in the old implementation we just showed Foldername
• Clicking on a file in the trashbin downloads the file but with incorrect extension
• Switching back to other file list does not work once entered the trash bin once
• Restore/delete permanently a file does not remove it from the list

Missing:

• Grid view not implemented
• Hide some columns on small screens
• Right-click does not work anymore

Enhancements:

• Deepen virtual scrolling performances
• Implement keyboard arrow/pageUp-Down navigation and focus management

Others:

• it feels strange that the right-click menu gets opened not directly at the tooltip but at where the expand button is triggered

@skjnldsv I am not sure if it is related to the trashbin migration but uploading any folder into the files app now results in conflicts and a NotFoundError files getting created multiple times. Looks like this is unrelated because I could reproduce this already on nc26 and nc25
