CC-5709: Airtime Analyzer

* Remove the "hidden" field from the REST blacklist, the analyzer needs to set it.
* Added import_status column messages in the recent uploads table
* Auto-refresh the recent uploads table while imports are pending
* Moved the file moving stuff to its own analyzer in airtime_analyzer
* Basic error reporting to the REST API in airtime_analyzer, needs
  hardeneing though
* Fixed a bug with the number of recent uploads
* Prevent airtime_analyzer from running if media_monitor is running
