Description & motivation

• Object results currently mirror log levels, but are used to report pass/fail information about collections of objects. Some users (@bjoernsteinhagen ) have requested the ability to also surface more information about "success" results with them.
• Frontend will fall back to INFO styling, or use new styling ones fix(automate): support success object result level speckle-server#3537 merged

Changes:

• Adds SUCCESS to enum and util like the others
