Phase 12 - Bruno API Tests Standardization
Convert all custom section builder tests to .yml format:
- preview-collection.bru → preview-collection.yml
- create-custom-section-manual.bru → create-custom-section-manual.yml
- create-custom-section-missing-fields.bru → create-custom-section-missing-fields.yml
- create-custom-section-rules.bru → create-custom-section-rules.yml
All Bruno tests now consistently use .yml extension across the project.
Tests cover:
- Preview collection with filter rules
- Create collection with manual book selection
- Validation of required fields
- Multiple filter rules with operators
