feat: Move actions filter to toolbar

[cpAdm]

Moves the 'action filters' to the toolbar:

• Only visible if on tab 'Actions'.
• Now also clicking the 'x hidden' text will open the dropdown
• Had to create a separate iconRef to make sure that the dropdown did not move when clicking action settings (since button position/width would change if 'x hidden' text would toggle)
• The 'should filter actions' test still passes
