Root cause: Cross-Origin-Opener-Policy is set to same-origin per default and will prevent parent or window.opener to be set
Solution: Set Cross-Origin-Opener-Policy to same-origin-allow popups

Use redirect instead of delivering index.html to prevent /ui paths in the future

Root cause: There are middlewares, which still use old redirects to /ui
Solution: To prevent 404s, we just serve the index.html

Root cause: Version has was updated before file cache
Solution: Keep all updates in one place and switch to new version at the same time

Root cause: If some of the UI containers is not available after successful start, the version update check might fail.
Solution: Add error handlers when manifests can not be fetched after startup

Root cause: Every readiness check triggered a cache warming
Solution: Move readiness to startup probe

Root cause: Due to the timeout, every request that was launched while fetching the previous manifests could led to another fetch and another cache.warmup
Solution: Be more synchronous

This prevents unnesessary large headers as the UI will filter for CSS files only

this is an implicit endpoint served by us.

remove /api prefix and be more restful. This should help to simplify ingress objects

first hit wins. This allows us to transparently use sourcemaps and other files that
are not part of the sources according to the vite manifest

this will mark the pod "ready", once the cache is warm.
This will remove the penality for the very first to this service, because
it will not receive any traffic until the cache is warm.

we want to have the changes rolled out, so we disable CSP headers for now and
will take care of them after the file_cache functionality has been rolled out

just for testing purposes, disable CSP for now until sha calculation is fixed

this currently doesn't really work as expected, but can be used as a base
to properly implement CSP for the scripts we "know" about.

the file cache is populated with data defined in the manifest files configured for
all components and will basically fetch everything from all components. This allows
us to use this manifest service as the only source of truth for UI related sources and
simplifies ingres setup a lot.

since it's still kind of small, it makes sense to switch to ESM, now.
