Workspace Trust Editor loads slowly and changes state during loading

Reloading workspace editor on a trusted project, 50% slower:

workspace-loading.mp4

Main issues in the recording, apart from the slow loading:

1. Loads in restricted mode for a long time, then suddenly toggled to trusted
2. Main trust/restricted panels take long to load and cause significant layout shift; even though they only contain few dynamic elements

I think to smooth this out without much change, for now, we just will wait to render until workspace is fully initialized (this is how the workbench indicators operate)

As the UI layout itself is mostly predictable in a rough shape, maybe using css grid could allow building a skeleton loading indicator; so the page doesn't stay blank for multiple seconds.

until the workspace trust state is resolved, nothing except the list of entries at the bottom is truly correct. while I agree we can do more polish on this, I don't think its worth doing this week.
