feat: testing framework POC

[brobro10000]

Initial consolidation of testing framework POC. Consolidate contexts, constants and API structures.

A reference tech is Pact that does a similar process with HTTP responses, while this frameworks hopes to mimic it with frontend context providers. It will allow for faster testing across features that have been consolidated.

Current POC is using Content Highlights. Currently WIP.

Pushes will look at the effect on test coverage and possible testing runtimes since we are reducing the overall amount of imports required per test.
