Annotate sync of enhancements

[lL1l1]

Description of the proposed changes

Annotate the data about how enhancements are synced.

Testing done on the proposed changes

• Logging the enhancement queue functions
• Looking for warnings related to the annotations.

Additional context

• The EnhQueueData class is declared in construction.lua as it is difficult to find how it gets put into the common enhancement table otherwise.
• Giving the Sync table a class brings up new undefined field warnings to solve for other sync features in the future

Checklist

• Changes are annotated, including comments where useful
• Changes are documented in the changelog for the next game version
