Suggestion: Extraction menus: If no existing params/etc, insert new ones at top of file in appropriate place

from #15193

[@levimatheri] If no existing params, insert before resources, etc. Probably follow comments -> metadata -> types -> params -> vars -> resources.

I.e., new params would be placed after comments, metadata and types, and before variables and resources. Similar for new variables and types

Start by reading issue #15193 and locating the extraction-menu entry point. Check how insertion behaves when params, variables, or types are absent. Done means new declarations follow the stated comments, metadata, types, params, vars, and resources ordering, including when earlier sections are missing.
