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.
