partially fix #19345
This PR add some `Link` methods for different objects. The `Link`
methods are not different from `HTMLURL`, they are lack of the absolute
URL. And most of UI `HTMLURL` have been replaced to `Link` so that users
can visit them from a different domain or IP.
This PR also introduces a new javascript configuration
`window.config.reqAppUrl` which is different from `appUrl` which is
still an absolute url but the domain has been replaced to the current
requested domain.
Even if we are not bundling with `vite` yet, we can use `vitest` in
place of Jest which brings a few benefits like not requiring to use
`NODE_OPTIONS` to run and having sane module resolution.
It's possible to also use `jest-extended` with vitest, but I opted to
not do so for now because it brings heavyweight dependencies and it was
trivial to just rewrite the affected matchers to be compatible.
This PR also removes 153 JS dependencies, which is certainly nice.
