IAV-1206/feat(faq): Strengthen FAQ Validation and Add Logging on Create/Update

Summary

Improved the FAQ feature by adding input validation, enforcing @Valid on the update endpoint, and adding structured logging to the service layer.

Changes

FaqRequestDto

• Added @NotBlank constraint on faqCategoryUid field to ensure a category is always provided on create and update requests

FaqController

• Added @Valid annotation on the FaqRequestDto parameter of updateFaq() to enforce validation on update requests (was already present on create)

FaqServiceImpl

• Added log.info() in createFaq() to trace incoming question and category
• Added log.info() in updateFaq() to trace incoming question and category

Type of Change

• Enhancement / improvement (non-breaking change that improves existing functionality)

How to Test

1. Call PUT /faqs/{faqUid} with a missing faqCategoryUid → expect 400 Bad Request
2. Call POST /faqs with a missing faqCategoryUid → expect 400 Bad Request
3. Call POST /faqs with valid payload → check logs for create trace
4. Call PUT /faqs/{faqUid} with valid payload → check logs for update trace

Notes

• No breaking changes to existing API contracts
• Validation is now consistent between create and update endpoints
