fix: create Odoo env directly in BDD fixture; fix _generate_template call

- pytest-odoo 2.x provides no 'env' pytest fixture; env only exists as
  self.env in TransactionCase subclasses. Build the env from odoo.registry()
  directly in the odoo_env fixture and rollback after each BDD scenario.
- _generate_template() takes positional args (res_ids, render_fields),
  not keyword args; remove 'fields=' keyword from all call sites.
