fix: Use user permissions for iframes instead of query parameters

[mofojed]

• Add UserUtils for fetching the User.
• Add ServerConfigBootstrap and UserBootstrap to bootstrap those objects into context.
• Remove query parameters for controlling user function in iframes; instead it is defined on the server.
• Fixes Features available for iframes are not the same as the ide by default #1337.

Tested by setting the following in the dh-defaults.prop and verified the functionality matched with what I set:
