Create "modal" component

ACs:

When I click on the language selector button popup should appear as on the screenshot
it should contain the "tabs" component with languages and currencies inside
there should be a grey transparent overlay on top of the rest of the screen
there should be a "x" close button
when i click on the overlay it closes the modal same as the close button
only inside of the popup should be scrollable, the rest of the screen should not be scrollable
animations are not necessary at this point of time
