Improve build-schema-match skills

- Give option Remove unused tables
- give suggestion for synthetic photometry and synthetic colors
- Dedicated table or entry in ModeledParamaters and ParametersList
- Are there any data which you will want to add to this database that is NOT in this input dataset that motivates adding any columns?

Start by locating the build-schema-match skill and the schema definitions it operates on. Review how unused tables, modeled parameters, parameter lists, synthetic photometry, and synthetic colors are currently represented. Done means the requested behavior and schema additions are resolved with an agreed design.
