test: add braze ecommerce recommended events coverage

[rudder-devbox]

Summary

• Added Braze destination fixture cases for valid device-mode useEcommerceRecommendedEvents: true and invalid non-boolean values.
• Added a focused validation assertion for the Braze UI field contract used as the source of truth for integrations-info mirroring.

Validation

• npm ci — passed
• pip3 install -r scripts/requirements.txt — passed
• npm test -- --runTestsByPath test/validation.test.ts --watchAll=false — validation tests passed; command exited non-zero due scoped-run global coverage thresholds
• npm test -- --runTestsByPath test/validation.test.ts --watchAll=false --coverage=false — passed
• npx --prefix /workspace/rudder-integrations-config jest --runTestsByPath /workspace/rudder-integrations-config/test/validation.test.ts --watchAll=false --coverage=false --testNamePattern="exposes the feature-flagged field for cloud, device, and hybrid modes" --runInBand --silent — passed
• PATH="/usr/local/bin:$PATH" npm run check:schema:destination -- braze — passed with existing schema-generator drift warnings
• npx --prefix /workspace/rudder-integrations-config prettier --check /workspace/rudder-integrations-config/test/validation.test.ts /workspace/rudder-integrations-config/test/data/validation/destinations/braze.json — passed
• npx --prefix /workspace/rudder-integrations-config eslint /workspace/rudder-integrations-config/test/validation.test.ts — passed
• Integration verification: npx jest --runTestsByPath test/validation.test.ts --runInBand --silent=false --coverage=false — exit 0; 1 suite passed, 6041 tests passed

⚠️ Known Issues

• The scoped Jest command without --coverage=false exits non-zero because this repo enforces 100% global coverage thresholds even though test/validation.test.ts passed.
• Braze schema generation still reports pre-existing drift unrelated to useEcommerceRecommendedEvents: additionalProperties recommendation, missing app/platform key fields in generated schema expectations, consent-management required-field diffs, and required-field insertions for app/platform key fields.
