🐛 Fix "unknown", never-end workflow and not displaying error message (#1978)
* Added try catch blocks to avoid endlessly running workflows * Added handling for subworkflows * ⚡ Fix one cause of "unkown" status of worklows with "main" mode * ⚡ Fix one cause of "unkown" status of worklows with "own" mode * ⚡ Fix one cause of "unkown" status of worklows with "queue" mode * Saving database recovery * 🐛 Fix issue that errors did not get saved correctly and also not displayed * ⚡ Save workflow timeout correctly as error * Adding error capture to queued jobs * ⚡ Mark canceled executions as not finished consistently across all modes Co-authored-by: Jan Oberhauser <jan.oberhauser@gmail.com>
