feat(auth): add PATCH /auth/profile endpoint for user profile updates

Implement user profile update with fullName, avatarUrl, and email fields.
Email changes include uniqueness validation and Email VO verification.
Follows existing DDD/CQRS patterns with cache invalidation.
19 unit tests covering handler logic and DTO validation.
