Update package path

[NourAlPha]

This pull request includes a comprehensive refactoring of the project structure to align with a new package naming convention (com.podzilla.cart) and introduces a minor configuration update to the application properties. Below is a summary of the most important changes:

Package Renaming and Refactoring:

• Renamed packages across all files: Updated the package structure from cart.* to com.podzilla.cart.* for better organization and to reflect the new naming convention. This change affects all files, including controllers, models, services, repositories, configuration, and exception handlers. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13] [14] [15] [16] [17]

• Updated imports: Adjusted all import statements to use the new package structure. For example, imports like cart.model.Cart are now com.podzilla.cart.model.Cart. [1] [2] [3]

Configuration Updates:

• Application properties: Added a new server.servlet.context-path=/api property to define a base context path for the application.

These changes improve the codebase's structure, maintainability, and scalability, ensuring better alignment with standard Java package naming conventions and preparing the application for future enhancements.
