Implement a lot of technical requirements for behavioural unit tests

Note: the crux of this was to make routing env-agnostic, and not based on URLs as magic strings, but instead something type-enforced.

Note: extension-based routes comply to same exact interface by "late-registering" their routes when installed. Routes are just injectables.

Note: another chunk of global shared state is no more.

Note: a lot of explicit side effects have been cornered to injectables.

Note: a lot of stuff has become reactive as part if this.
