fix: remove dbname from sites and apis export config

The dbname column has DEFAULT current_database() which captures the
random test database name during introspection, causing non-deterministic
output in generated migration files (apis.sql, sites.sql).

By removing dbname from the export config, the generated INSERT statements
won't include this column, and it will use its DEFAULT at deploy time.
