refactor: Apply cache fixes directly to existing runner configs

- Update all runner configuration files with cache networking fixes:
  - config_docker.yaml
  - config_heavy.yaml
  - config_light.yaml
  - config_security.yaml
- Remove separate config_cache_fixed.yaml file
- Update troubleshooting scripts to use updated configs
- Update documentation to reference existing config files

All runner configs now have:
- Fixed cache host: host.docker.internal
- Fixed cache port: 44029
- Host networking for better container connectivity

This provides a cleaner approach by updating existing configs
instead of maintaining a separate fixed configuration file.
