finishes search feature with multiple filters and sorting

[taha-qam]

Changes

• Added filters for categories (can have multiple categories)
• Added filters for price (in a range)
• Added filters for condition (new, used, and more)
• Added sort option for price (ascending or descending)
• Added sort option for data added (newest to oldest)
• Added clear filters option to go to default state
• Worked on frontend, got a semblance of figma design for marketplace search
• Changed colors to match figma in config file (ucsd-gold, ucsd-blue, etc)
• Added dropdown for filters and for categories, works fine and in tandem
• Moved sorting to under the marketplace search to match figma design
• Added colors and LowPriceCenter title matching figma design

Testing

I ran the code and tested search options, filters myself with products. To make sure it would work with Abas's code, I copied his changed files into my code, and made any changes needed in my code to have it work with his. From what I have seen my filtering/sorting logic works with his frontend.

AS OF 2/18: Code backend works with Abas's code, frontend should not interfere with his work. Tested my features and they work as expected

• TODO (AS OF 2/18)
• search in tandem with filtering/sorting (right now one or the other)
• fix up UI to match with addProduct, and update with new UI changes
• maybe clean up UI a bit more
