feat: Refactor user context handling and service methods

- Updated middleware to fetch user and tenant models by ID and set them in context. - Refactored common service methods to accept userID as a parameter instead of extracting from context. - Modified content service methods to include userID as a parameter for better clarity and performance. - Adjusted coupon, creator, notification, order, tenant, user, and wallet services to utilize userID directly. - Enhanced context key constants for improved readability and maintainability.
