[BISERVER-9414] - Multiple updates to the Scheduling

* Add output path in the schedule perspective table.
* Make sure that only the link responds to clicks, not the entire cell.
* If the output location is invalid, delete the old schedule job and create a new one with the updated fallback location. This ensures that the schedule perspective reflect the fallback output path, not the original (invalid) path
