/**
* This module provides a urlState() function returning a singleton UrlState, which represents
* Grist application state as encoded into a URL, and navigation functions.
*
* For example, the current org is available as a value or as an observable:
*
* urlState().state.get().org
* computed((use) => use(urlState().state).org);
*
* Creating a link which has an href but changes state without reloading page is possible with:
*
* dom('a', urlState().setLinkUrl({ws: 10}), "...")
*
* Grist URLs have the form:
* <org-base>/
* <org-base>/ws/<ws>/
* <org-base>/doc/<doc>[/p/<docPage>]
*
* where <org-base> depends on whether subdomains are in use, i.e. one of:
* <org>.getgrist.com
* localhost:8080/o/<org>
*
* Note that the form of URLs depends on the settings in window.gristConfig object.

(core) move more tests to grist-core Summary: * Tie build and run-time docker base images to a consistent version (buster) * Extend the test login system activated by GRIST_TEST_LOGIN to ease porting tests that currently rely on cognito (many) * Make org resets work in absence of billing endpoints * When in-memory session caches are used, add missing invalidation steps * Pass org information through sign-ups/sign-ins more carefully * For CORS, explicitly trust GRIST_HOST origin when set * Move some fixtures and tests to core, focussing on tests that cover existing failures or are in the set of tests run on deployments * Retain regular `test` target to run the test suite directly, without docker * Add a `test:smoke` target to run a single simple test without `GRIST_TEST_LOGIN` activated * Add a `test:docker` target to run the tests against a grist-core docker image - since tests rely on certain fixture teams/docs, added `TEST_SUPPORT_API_KEY` and `TEST_ADD_SAMPLES` flags to ease porting The tests ported were `nbrowser` tests: `ActionLog.ts` (the first test I tend to port to anything, out of habit), `Fork.ts` (exercises a lot of doc creation paths), `HomeIntro.ts` (a lot of DocMenu exercise), and `DuplicateDocument.ts` (covers a feature known to be failing prior to this diff, the CORS tweak resolves it). Test Plan: Manually tested via `buildtools/build_core.sh`. In follow up, I want to add running the `test:docker` target in grist-core's workflows. In jenkins, only the smoke test is run. There'd be an argument for running all tests, but they include particularly slow tests, and are duplicates of tests already run (in different configuration admittedly), so I'd like to try first just using them in grist-core to gate updates to any packaged version of Grist (the docker image currently).
