Add search by category/item page

[Kaptard]

Useful as an alternative to direct input search and when users need to sort data.

General things to note:

• Will be the page people see when entering items that couldn't be found, so it must be search-input compatible
• May contain a rectangular drill-down chart above results when filters are selected. (After rework)
• Should be accessible from landing page, sidebar and anywhere else where the search component is implemented.

Filters:

• Search by input
• Search by tags
• Filter by price, ducats, supply, demand, region, trade source (all ascending/descending) (put in dropdown menu?)

API considerations:

• Use the existing fuzzy matching for input search
• Extend fuzzy matching for searches by tag
• Add endpoints to look up filtered target data based on item list from fuzzy search

Search result page has been added. Item page still missing, but should be easy to base on the search page as it's supposed to do the same thing fundamentally.

Moving to post-rework issues. The important part of this was the search page. We can look at the items page at a later date.
