fix: move odoo_env fixture to root conftest.py

conftest.py inside the addon directory causes pytest to import the
package directly (bypassing the odoo.addons.* namespace), triggering
an AssertionError in Odoo's metaclass. Moving the fixture to the
repo-root conftest.py avoids the import path issue.
