Patch FHIR Resource

Partially updates a FHIR resource on the specified provider using JSON Patch operations as defined in RFC 6902.

The request body should contain an array of JSON Patch operations. Each operation specifies:

• op: The operation type (add, remove, replace, move, copy, test)
• path: JSON Pointer to the target location in the resource
• value: The value to use (required for add, replace, and test operations)

The request is proxied to the configured FHIR server with appropriate authentication headers.
