Bridg rules assume id type is always string

[JoeRoddy]

Add support for Int id's. Bridg assumes user ids are always strings, but they can be ints, possibly more types.

• Lazy quick implementation would be to just change the type to string | number
• Ideally we would inspect the project's prisma schema and dynamically infer the primary key's type from that and set that as the TS type of the userId
