feat(web): move search options into a modal

Description

Moving the search options into a modal, rather than displaying them below the search bar. Benefits of this change include:

• Guaranteed space in all screen sizes for the filters
• Focus trapping, so users can never accidentally tab off the end of the filters
• Automatically return focus back to the button in the search bar when the modal is closed

Thank you for the PR. One change I think would make the model look better is incorporating the scroll bar inside the modal and appearing below the curved corner. Please see the example below
