web: provide a test framework (#9681)

* web: fix esbuild issue with style sheets

Getting ESBuild, Lit, and Storybook to all agree on how to read and parse stylesheets is a serious
pain. This fix better identifies the value types (instances) being passed from various sources in
the repo to the three *different* kinds of style processors we're using (the native one, the
polyfill one, and whatever the heck Storybook does internally).

Falling back to using older CSS instantiating techniques one era at a time seems to do the trick.
It's ugly, but in the face of the aggressive styling we use to avoid Flashes of Unstyled Content
(FLoUC), it's the logic with which we're left.

In standard mode, the following warning appears on the console when running a Flow:

```
Autofocus processing was blocked because a document already has a focused element.
```

In compatibility mode, the following **error** appears on the console when running a Flow:

```
crawler-inject.js:1106 Uncaught TypeError: Failed to execute 'observe' on 'MutationObserver': parameter 1 is not of type 'Node'.
    at initDomMutationObservers (crawler-inject.js:1106:18)
    at crawler-inject.js:1114:24
    at Array.forEach (<anonymous>)
    at initDomMutationObservers (crawler-inject.js:1114:10)

(anonymous) @ crawler-inject.js:1114
initDomMutationObservers @ crawler-inject.js:1114
(anonymous) @ crawler-inject.js:1549
```

Despite this error, nothing seems to be broken and flows work as anticipated.

* web: provide a test framework

As is typical of a system where a new build engine is involved, this thing is sadly fragile. Use the
wrong import style in wdio.conf.js and it breaks; there are several notes in tsconfig.test.conf and
wdio.conf.ts to tell eslint or tsc not to complain, it's just a different build with different
criteria, the native criteria don't apply.

On the other hand, writing tests is easy and predictable. We can test behaviors at the unit and
component scale in a straightforward manner, and validate our expectations that things work the way
we believe they should.

* Rolling back a reversion.

* Adjusting paths to work with tests.

* add ci to test

* web: patch spotlight on the fly to fix syntax issue that blocked storybook build

This should be a temporary hack.  I have an [open
issue](https://github.com/getsentry/spotlight/issues/419) and [pull
request](https://github.com/getsentry/spotlight/pull/420) with the
Spotlight people already to fix the issue.

* Somehow missed these in the merge.

* Merge missed something.

* Fixed an issue where npm install and npm ci had different shell script behaviors.

* Removed debugging messages.
