Enforce YAML Field Ordering

[nasbench]

The change adds a configurable .yamlfieldorder definition and a new enforce_yaml_field_order.py utility, integrates field-order enforcement into pre-commit and YAML validation CI, and updates the workflow triggers so validation changes are tested automatically.

Existing detection YAMLs are also reordered to conform to the new standard without changing their underlying detection content.

This improves consistency across security content, reduces formatting drift, and makes YAML files easier to review and maintain.

Some vibe coding was used for the writing of the script. But it was inspired by my previous YAML script which was human written for the most part. So this is kinda of okay by my standards
