* fix: handle errors from service.NewService() in startup code Previously, both HTTP and Wails startup code ignored errors from service.NewService(ctx) using blank identifier (_), which could cause panics later if NewService fails (e.g., unable to connect to postgres database). Now properly handle the error and exit gracefully with a fatal log message when service initialization fails. * fix: compile error --------- Co-authored-by: Roland Bewick <roland.bewick@gmail.com>
