Migrate Airtable PK from ProjectName to MongoDB projects._id

[idiom-bytes]

Currently the PK is set to ProjectName, this blocks us from making ProjectName editable. Let's dump all projects._id fields from mongo, insert those into a new PK for Airtable, and keep ProjectName as editable.

DoD:

• [ ] Mongodb project._id is new PK inside of Airtable
• [ ] All views and outputs from Airtable work with the new PK
