List of changes made

• a button was added to switch between showing and not showing that section. The default is to not show it.
• a button in each hidden row was added to move the row back to the list of recent rows
• the functionality to toggle favorites was adjusted so that even hidden rows can become favorites in one click

Screenshot of the fix

Testing

• Go to the report page
• Try to toggle the hidden-section with the new button
• If you don't have hidden rows yet, try to hide some from the recent-section
• try to un-hide a hidden row by clicking on the double-arrow up
• try to make a hidden row a favorite by clicking on the star
• try to reload the page and make sure the right favorites and hidden rows are loaded. (Using the toggle icons for favorite/hide/un-hide on the left of each row should save immediately)

Works fine, also with keyboard nav.
Though, somehow the "labelledby" for the day sum seems to have re-entered in this code. This should be fixed - again - before merging this code.
