Add connection URL output when creating or resetting Postgres roles

Display credentials in a vertical layout with DATABASE URL when
creating a role or resetting a role's password. This makes it easier
for users to copy the connection string directly.

Human output:
  ID                 role-abc123
  NAME               my-role
  USERNAME           my-role_abc123
  PASSWORD           secretpass123
  ACCESS HOST URL    pg.psdb.cloud
  DATABASE URL       postgresql://...

JSON/CSV output includes the new database_url field.

The connection URL follows the format:
postgresql://username:password@host:port/postgres?sslmode=verify-full
