npm: update express to 5.1

Ref #8529

This gives me headaches. The core issue is there are no longer those flexible regex routes. Rather a more strict system, i.e. path-to-regexp updated. One place where I'm stuck is the proxy setup for projects. The idea I have is to create a small middleware, which checks if the supposed project ID is actually an UUID – otherwise to pass on internally to the next route. router level middleware This also implies that the "string-regex" passed to initUpgrade needs to be different than the more general path for the route.

What I got to work is e.g. the index page, loading frontend, redirecting to specific frontend pages, etc. The websocket connection doesn't work though. Some detail must be off.

Also, just while running the dev server, I get weird sudden crashes like that:

Panic occurred at runtime. Please file an issue on GitHub with the backtrace below: https://github.com/web-infra-dev/rspack/issues
Message:  should mgm exist

What I haven't even started to look into is the api/v2 endpoint:

 ✓ Compiled /api/v2 in 39s (10082 modules)
 ⨯ [TypeError: Cannot set property query of #<IncomingMessage> which has only a getter] {
