More fixes after switching to JSON

In commit 254b71ed dashboard switched to JSON to improve efficiency. While doing that several functions and strings were renamed to point to the new format. Unfortunately there are still references to YAML in several places which are misleading.

Fix remaining references to YAML to avoid confusions.

Additionally, since now dashboard shows the list of packages unsorted, force the sorting before rendering.
