Use CSP to block inline JS content in editor (#3939)
* Revert "Sanitize field content in editor"

This reverts commit 1c156905f8.

* Use CSP to block inline JS content in editor

This blocks inline scripts, scripts in the media folder, and
handlers like onclick in the editor. This is nicer than the previous
solution - it doesn't make any permanent changes, and leaves other
content like SVGs alone. Thanks to Nil Admirari for the suggestion.

Harden access to internal API (#3925)
* Sanitize field content in editor

The editor already strips script tags from fields, but was allowing
through Javascript in things like onclick handlers. We block this now,
as the editor context has access to internal APIs that we don't want to
expose to untrusted third-party code.

* Require an auth token for API access

We were previously inspecting the referrer, but that is spoofable,
and doesn't guard against other processes on the machine.

To accomplish this, we use a request interceptor to automatically
add an auth token to webviews with the right context. Some related
changes were required:

- We avoid storing _page, which was leading to leaks & warning on exit
- At webview creation (or set_kind() invocation), we assign either
an authenticated or unauthenticated web profile.
- Some of our screens initialize the AnkiWebView when calling, e.g.,
aqt.forms.stats.Ui_Dialog(). They then immediately call .set_kind().
This reveals a race condition in our DOM handling code: the webview
initialization creates an empty page with the injected script, which
causes a domDone signal to be sent back. This signal arrives after
we've created another page with .set_kind(), causing our code to think
the DOM is ready when it's not. Then when we try to inject the dynamic
styling, we get an error, as the DOM is not ready yet. In the absence
of better solutions, I've added a hack to set_kind() to deal with this
for now.

* Provide AnkiWebPage init defaults for existing add-on callers

* Inject bridge script when profile set-up skipped

Some add-ons fully override AnkiWebPage.__init__ and thus depend on _setupBridge injecting the JS bridge script.

With this change we account for these cases, while giving add-ons the opportunity to look for solutions that do not require overriding AnkiWebPage.__init__ completely.

* Add some missed pages/endpoints (thanks to iamllama)

* Avoid sending API key for remote resources

Thanks to Abdo for the report

Switch to SvelteKit (#3077)
* Update to latest Node LTS

* Add sveltekit

* Split tslib into separate @generated and @tslib components

SvelteKit's path aliases don't support multiple locations, so our old
approach of using @tslib to refer to both ts/lib and out/ts/lib will no
longer work. Instead, all generated sources and their includes are
placed in a separate out/ts/generated folder, and imported via @generated
instead. This also allows us to generate .ts files, instead of needing
to output separate .d.ts and .js files.

* Switch package.json to module type

* Avoid usage of baseUrl

Incompatible with SvelteKit

* Move sass into ts; use relative links

SvelteKit's default sass support doesn't allow overriding loadPaths

* jest->vitest, graphs example working with yarn dev

* most pages working in dev mode

* Some fixes after rebasing

* Fix/silence some svelte-check errors

* Get image-occlusion working with Fabric types

* Post-rebase lock changes

* Editor is now checked

* SvelteKit build integrated into ninja

* Use the new SvelteKit entrypoint for pages like congrats/deck options/etc

* Run eslint once for ts/**; fix some tests

* Fix a bunch of issues introduced when rebasing over latest main

* Run eslint fix

* Fix remaining eslint+pylint issues; tests now all pass

* Fix some issues with a clean build

* Latest bufbuild no longer requires @__PURE__ hack

* Add a few missed dependencies

* Add yarn.bat to fix Windows build

* Fix pages failing to show when ANKI_API_PORT not defined

* Fix svelte-check and vitest on Windows

* Set node path in ./yarn

* Move svelte-kit output to ts/.svelte-kit

Sadly, I couldn't figure out a way to store it in out/ if out/ is
a symlink, as it breaks module resolution when SvelteKit is run.

* Allow HMR inside Anki

* Skip SvelteKit build when HMR is defined

* Fix some post-rebase issues

I should have done a normal merge instead.
