platform/webui: add scenario description, show it in the Scenario page's list

Browse Source 
ScenarioSpec gains an optional "description" field. Listing (both
ListLocalScenarioFiles and ListScenarioFilesOnRemovableMedia, via the new
scenarioDescription helper) reads it out of each file without requiring
full ParseScenarioJSON validation to succeed, so a listing never hides a
scenario over an unrelated validation issue. The webui Scenario page now
renders Name/Description/Found-on/Run instead of just Name/Found-on — a
bare filename rarely tells anyone but the author what a scenario actually
does.
