feat(apps): OBD2 placeholder rail item (launchpad for the parked OBD2 project)

Adds an OBD2 item to the Apps rail; with no records UI deployed yet it links to
the OBD2 Telemetry project + tasks and the research/wiki page rather than
embedding. Swap to embedView once LubeLogger/Tracktor is up. → 2.1.1.
