Summary

This pull request addresses several issues related to patient registration, particularly when the application is used offline and when custom field definitions are involved. The key changes and enhancements are as follows:

1. Caching Patient Field Definitions: Previously, the patient registration process relied on fetching field definitions from the server every time a new patient was registered. This led to errors and inconsistencies when the application was used offline. In this pull request, we introduce caching for patient field definitions. Now, these definitions are fetched and stored locally, reducing errors and improving the user experience.

2. Offline Patient Registration with Custom Field Definitions: With this update, users can seamlessly register patients while offline, even when custom field definitions are present in the configuration. This functionality ensures that the application remains robust and user-friendly in various scenarios.

3. Improved Offline Registration Workflow: In the past, users were required to visit the registration page at least once to enable offline patient registration. This requirement has been removed. All necessary resources, including field definitions, are now cached during the startup of the application, allowing users to register patients offline right from the start.
