fix: use Promise<Client> type for connectPromise instead of .then(() => {})

Updated the type annotation to match @types/pg@8.18.0 where Client.connect()
now correctly returns Promise<Client> (was incorrectly typed as Promise<void>
in @types/pg@8.16.0). No behavioral change — the runtime always returned
Promise<Client>.
