Add initial page structure for Clients, Orders and Services pages

[reenatoteixeira]

This pull request refactors the Clients, Orders, and Services pages to introduce reusable table components, add entity-specific type definitions, and improve the overall user interface for managing these entities. The changes lay the groundwork for CRUD operations by adding placeholder data, action buttons, and TODO comments for future database integration and routing.

Key changes include:

UI and Table Refactoring:

• Replaced the previous static and placeholder content on ClientsPage, OrdersPage, and ServicesPage with a consistent table-based layout using the shared Table component. Each page now supports search, pagination, and action buttons for editing and deleting entries, with "New" buttons to add new entities. [1] [2] [3] [4] [5] [6]

Type Definitions and Exports:

• Added new TypeScript interfaces for Client, Order, and Service entities, ensuring type safety and consistency across modules. [1] [2] [3]
• Exported these types from their respective index.ts files for easier imports throughout the codebase. [1] [2] [3]

Preparation for CRUD Operations:

• Added placeholder arrays and TODO comments in each entity page to indicate where data fetching and CRUD logic will be implemented in the future. Action buttons for edit and delete are wired with placeholder handlers and routes. [1] [2] [3]

These changes establish a scalable foundation for entity management and set up clear next steps for database integration and routing.
