Useful in moderation scenarios where you want to quarantine media and can quickly/easily look at the data attribute on the media (image/videos). Or simply write a little script to extract all of the `data-mxc-url` and `data-thumbnail-mxc-url` attributes.
ex.
```
<img src="http://localhost:8008/_matrix/media/r0/thumbnail/my.synapse.server/TEyTVUNgvUQZcXlrLwgGfbcp?width=400&height=266&method=scale" alt="Stormclouds.jpg" title="Stormclouds.jpg" data-mxc-url="mxc://my.synapse.server/kxibKhxRfTvFWyuWwWvFuBtE" data-thumbnail-mxc-url="mxc://my.synapse.server/TEyTVUNgvUQZcXlrLwgGfbcp" style="max-width: 400px; max-height: 266px;">
```
- Default to a nice `[matrix]` banner
- There is room for improvement here when the Matrix Public Archive gets it's own logo (https://github.com/matrix-org/matrix-public-archive/issues/94) and maybe says "Matrix Public Archive" somewhere in the banner.
- This is good enough for now (and certainly better than downstream previews using the first image on the page).
- For rooms, it will use the room avatar
Part of https://github.com/matrix-org/matrix-public-archive/issues/202
Image is sized to 1200x630 to match conventions of `og:image`.
Crafted the banner image by modifying the header on the room directory homepage and taking a node screenshot. Page zoom @ 175%
Fix `debugActiveDateIntersectionObserver` checkbox being checked by default when the value was actually `null`.
Now we properly only care about explicit `'true'`, `'false'` from local storage.
Before:
```
<input id="debugActiveDateIntersectionObserver" type="checkbox" checked="null">
```
After:
```
<input id="debugActiveDateIntersectionObserver" type="checkbox">
```
Set `X-Date-Temporal-Context: [past|present|future]` header for easy cache rules:
- Cache `past` things heavily
- Cache `present`/`future` things for 5 minutes
This accomplishes the goal we set out for:
> - We can cache all responses except for the latest UTC day (and anything in the future). ex. `/!aMzLHLvScQCGKDNqCB:gitter.im/date/2022/10/13`
> - For the latest day, we could set the cache expire after 5 minutes or so
>

And this way we don't have to do any fancy date parsing and comparison from the URL which is probably not even possible Cloudflare cache rules.
Who knows why we can't capture these errors via the more conventional `child.on('error', (err) => { })` listener 🤷

Don't jump calendar around for events which appear in the future compared to the timestamp in the URL.
This sort of situation occurs often for Gitter imported historical rooms where we have a bunch of history that is timestamp massaged intermixed with a bunch of join events which we couldn't timestamp massage at the time.
Fix https://github.com/matrix-org/matrix-public-archive/issues/182
- Like getting all of the dependencies for a given entry point
- And the favicons
Also fix the problem where `server/hydrogen-render/render-page-html.js` was calling `getFaviconAssetUrls()` right away before the client build had a chance to generate `dist/manifest.json` and result in `Error: Cannot find module '../../dist/manifest.json'`
- Rename `public` -> `client` so it doesn't get copied automagically as-is (without hashes which we want for cache busting), https://vitejs.dev/guide/assets.html#the-public-directory
- We still build the version files to `public/` so their copied as-is and Vite handles it for us (so we can use `emptyOutDir`)
- Use a multiple entrypoint `.js` Vite build so things can be more intelligently bundled and take less time
- We aren't using library mode because it doesn't minify or bundle assets
- Using hash asset tags for cache busting. Hash of the file included in the file name
- We lookup these hashed assets from `manifest.json` that Vite builds (https://vitejs.dev/guide/backend-integration.html) to serve and preload
- In terms of optimized bundles, I know the current output isn't great now but will have to opt to fix that up separately in the future. Tracked by https://github.com/matrix-org/matrix-public-archive/issues/176
We already read it once for the `/health-check` endpoint and cached the response but this way we can use `getVersionTags()` everywhere without worrying about it.
Also, it's no longer `async` so we can use it in things like Express route paths and CDN asset tags more easily.
