This PR introduce a functionality to search the result list:

• Clicking "/" will show a search input at the bottom of the list, and to return to the result list
• This will not mutate the original list; it should merely allow the user to search files and do actions on individual files
• There should be an option to reset the filtered list
• if the global process replace is actioned, there should be a modal confirming the action, to not replace all the files.
