feat: Generate types for DB schema and setup kysely

Run the kysely-codegen task to regenerate the types.
Don't forget to reformat the generated code to follow our linting rules.

Since this is using DB introspection, you have to specify a DB
connection string via the --url param or the DATABASE_URL env var:
