Major filter refactor

[EDsCODE]

Changes

Please describe.

• use mixin to modularize filter objects. This will allow clear additions/removal to a filter and compartmentalize where the logic/defaults are handled
• add dedicated path filter
• to_dict arguments will be handled within scope

Checklist

• Some way to create a mixin factory? without losing type clarity
• Make sure that to_dict and tojson produce filters that are cache consistent
• All querysets/queries filter by Organization, by Team, and by User
• Django backend tests
• Jest frontend tests
• Cypress end-to-end tests

I fiddled with a factory pattern here but resorted to doing a more straightforward pattern for now

Note - we can probably automatically generate this method as well if we go the mixin route. :)
