feat: Improved Ingredient Matching (#2535)

* added normalization to foods and units

* changed search to reference new normalized fields

* fix tests

* added parsed food matching to backend

* prevent pagination from ordering when searching

* added extra fuzzy matching to sqlite ing matching

* added tests

* only apply search ordering when order_by is null

* enabled post-search fuzzy matching for postgres

* fixed postgres fuzzy search test

* idk why this is failing

* 🤦

* simplified frontend ing matching
and restored automatic unit creation

* tightened food fuzzy threshold

* change to rapidfuzz

* sped up fuzzy matching with process

* fixed units not matching by abbreviation

* fast return for exact matches

* replace db searching with pure fuzz

* added fuzzy normalization

* tightened unit fuzzy matching thresh

* cleaned up comments/var names

* ran matching logic through the dryer

* oops

* simplified order by application logic
