config: disable all heuristic gap-fill in hybrid mode demos

Manifests define complete entity structure - all heuristic entities
from runtime discovery are noise. Disable across all 3 demos:
- create_synthetic_components: false (pre-existing)
- create_synthetic_areas: false (needed for turtlebot3 Gazebo nodes)
- allow_heuristic_areas: false
- allow_heuristic_components: false (needed for turtlebot3 ros_gz_sim)
- allow_heuristic_apps: false (needed for _param_client_node orphan)
