Multiple small admin dashboard fixes (#12153)

* Remove spurious spacing between Maintenance Operations and its table on dashboard
* Prevent (EXTRA string) comments in Task headers
* Redirect tasks started from monitor page back to monitor
* Fix #12107 - redirects from process cancel should use AppSubUrl
* When wrapping queues set the name correctly
