[fix-2940][framework]: Add lazy caching of http codes for error handling and fix any broken Http error messages

[keon94]

Summary

1. Reworked the Type.Combine logic for combining multiple errors
2. Made some improvements to the Error interface as far as getting message information about that error, and returning an extended error JSON to the front-end with the structure:

{
 "success": false,
 "message": "some string",
 "causes": ["cause1 string", "cause2 string", "cause3 string"]
}

3. All Http codes now supported, not just the statically provided Types (fixes [Bug][Core] Database Migration Required uses Wrong Status Code 500  #2940)
4. The work from (1) fixes the problem in [Bug][Core] GitHub Plugin PAT Token TEST Degraded #3031

Does this close any open issues?

Closes #2940, #3031
