[main < T324] Reliable llm_util output

[antepusic]

Description

This PR addresses the issue of checks failing because the order of properties in llm_util.schema('prompt_ready') is not deterministic. The fix is to sort the properties before outputting them, and e2e tests are updated to reflect that.

You are missing newlines at the end of some tests, but that can be added after tests pass.

Also it should probably be added to the schema documentation that the properties are sorted now.
