fix: Refactored styled components to prevent multiple creations in render method

[sampathBlam]

• Fix warnings related to creation of styled components in render method
• Created separate component files and wrapped the styled components in them
• src: https://github.com/styled-components/styled-components/issues/3015#issuecomment-585346714
• Warning content :

  The component X with the id of Y has been created dynamically.
  You may see this warning because you've called styled inside another component.
  To resolve this only create new StyledComponents outside of any render method and function component 

• Fix unique key related warning for filters
