[harshiill]

This pull request introduces a new Health Center module to the application and refactors several parts of the existing Health Center compounder codebase for improved maintainability, user experience, and code consistency. Key changes include the addition of a dashboard for compounders, improvements to error handling and data validation, and the consolidation of breadcrumb imports. There are also enhancements to feedback, history, and patient update flows.

Health Center Module Integration:

• Added the HealthCenter module and route to the main application, enabling /healthcenter/* navigation. [1] [2]
• Introduced CompounderDashboard.jsx, providing a user-friendly dashboard for compounders to manage patients, stock, schedules, feedback, announcements, and more.

Code Refactoring and Consistency:

• Refactored all breadcrumb imports in Health Center compounder components to use a unified path: ../../components/common/Breadcrumbs. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10]

API and Data Handling Improvements:

• Replaced direct axios calls with dedicated API utility functions (e.g., createAnnouncementApi, getAnnouncementsApi) for announcements, improving code modularity and maintainability. [1] [2]
• Enhanced data validation and error handling in feedback, history, and patient update components to handle unexpected or malformed API responses more gracefully. [1] [2] [3] [4] [5] [6]

User Experience Enhancements:

• Added immediate feedback and page reloads upon successful doctor/pathologist addition or removal, ensuring the UI reflects the latest state. [1] [2] [3] [4]
• Improved patient update flow by fetching and managing a list of patients, and by providing clearer error messages. [1] [2] [3]

These updates collectively improve the modularity, usability, and robustness of the Health Center compounder module.
