* Endpoint page: improve formatting
Cherry-picked from #2906 (conflicts with that)
Partly addresses #2837 but does not resolve it
* Add badge customizer to the endpoint page
* Clean lint
This removes `LONG_CACHE` and its descendants, which was a feature that added `?maxAge` to the live preview badges in the frontend. Since they are all static that is no longer needed, as the static badges all have longer cache timeouts regardless.
The static previews don't support the social badges. Adding that lets us remove support for `exampleUrl`. Close#2479.
This includes `style` and `namedLogo` in the service-definition export and updates the frontend to use it. To accomplish this, it passes `namedLogo` through `coalesceBadge`. After logo resolution is moved to `makeBadge` this duplication can be removed, as `logo` will no longer be needed in the result of `coalesceBadge`.
The intention of wrapping HTML in an `__html` is to avoid accidentally unsafe rendering of something that is non-html.
Including this in the definition export solves the problem, and does not seem too onerous for other possible users of that file.
Close#2725
- With examples using `pattern`s, allow building the URL from its component parts, including the query string.
- Provide a button to copy the link, with an animation.
To enable this for other badges, convert them to use a `pattern`: #1961.
