Clean up filter components

[doug-s-nava]

Summary

A few things that would simplify our filter components for future use and expansion:

• move accordion content and title functions into their own components
• memoize functionality where possible
• improve prop naming / reduce prop drilling where possible
• try to split out filter section into more bite sized pieces
• add more comprehensive unit testing around dynamic functionality

Acceptance criteria

functionality around search filter accordions is

• more fully tested
• easier to understand
• more modular and flexible for future use
• more performant
