HMR/live-reload fixes (webpack-dev-server)

[ixrock]

As part of #6948 since incorrectly rebased from first monorepo times.

Current master: only manual page refresh, e.gCmd+R (example of editing welcome.tsx)

PR changes:

Does some auto page-reloading, but doesn't respect cluster frame location, therefore leads to updating page to global catalog page which is not desired, but better then nothing. (needs to be improved in follow up PRs)

Current error leading to full page reload instead of HMR (caught from video above):

@jakolehm why do we need this proxy at all? any ideas? it seem like works fine without this..

Not very useful with stated behavior: always reloading the page and moving to Catalog. Much easier to hit Cmd+R while in Cluster view because moving back from Catalog requires "bigger effor".

Also, HMR works as expected now when changing CSS.

@aleksfront Actually I think it should do page reloading in case when HMR cannot be applied and it works fine for app's global window (e.g. it keeps latest page, /welcome, /settings) but doesn't work inside cluster iframe properly for some reasons..
And that thing should be fixed or at least ignored (handling HMR inside iframe differently), so you could do manual page reloading whenever you want.

Any ideas why this error happens leading to full page reload?
