Create clean seed files

[flexbox]

as a dev,
I can nuke database and start from fresh,
so that i can recover from a disaster

Actually we import .csv files for the DB —example with places #9
This is not ideal.

We should have seeds for the database https://supabase.com/docs/guides/local-development/seeding-your-database

• clean the places database on supabase
• create the seed file
