Mail template + helpers (_fc_alert_*, _fc_recent_failure_count, _fc_send_failure_alert) wired into _check_credentials so that crossing the consecutive-failure threshold within the window queues exactly one mail.mail per attempted login per 60-minute cooldown. Master switch x_fc_login_audit_alert_enabled honoured. Recipients are members of base.group_system with a non-empty email and share=False; the __system__ superuser is excluded by Odoo''s default user filter. Tests (3 new, 22 total green): test_failure_burst_queues_one_email test_cooldown_suppresses_second_alert test_alert_disabled_master_switch setUp ensures base.user_admin has an email (fusion-dev''s admin user ships without one; the only user with an email is __system__, which is filtered out of standard res.users searches).
