Refactor error handling and IHttpContextAccessor usage

Simplified error message construction in RoleApplication.cs by
removing redundant properties. Refactored IHttpContextAccessor
registration in Program.cs to use the service provider after
app initialization. Removed redundant no-op code in
NullFaceEmbeddingNotificationService.cs.
