fix(badblueprint): use harness paths in scenario TOML

[lemontreeran]

Motivation

• Ensure the badblueprint scenario references the real harness orchestrator and agent scripts so the Colab notebook FULL SCORING preflight can run without manual patching.

Description

• Updated scenarios/security_arena/submissions/purple_vanguard/badblueprint/scenario_badblueprint.toml to replace the green agent command with python scenarios/security_arena/orchestrator.py ... and to replace attacker/defender commands with python scenarios/security_arena/agents/generic_attacker.py ... and python scenarios/security_arena/agents/generic_defender.py ..., leaving all other TOML parameters unchanged.

Testing

• Ran automated checks that scenarios/security_arena/orchestrator.py, scenarios/security_arena/agents/generic_attacker.py, and scenarios/security_arena/agents/generic_defender.py exist and verified the TOML no longer contains vendor/agentbeats-lambda/ or scripts/run_badblueprint_orchestrator.py, and all checks passed.
