feat: added the ListSearchComponent

[kristinetuazon]

This PR partially resolves issue #45.

In this PR I have created a main component called ListSearchComponent in the components folder. ListSearchComponent has the following components in it:
-ListModal (main container of the component)
-ListGrid (controls how the cards are laid out on the component)
-ListCard (how the information is being rendered)
and their corresponding stylesheets

I created the component apart from the codebase initially, thus its lack of interconnectivity. However, this component should be developed alongside with the filter component and its features. Since the filter system is non-existent, I focused on styling instead of any functionality at this point.

Other things to work on:

• This component is optimized for the mobile version of the web app. A responsive web app version still needs to be made.
• Rendering of all the necessary information is still not available in the card component.
• Having the component itself properly integrated into the application alongside using the code style of the code base.
