grblhal init: boot-time controller-mode dispatch

Browse Source 
The init script consults controller_mode in /data/forgefirm.conf:
'cloud' (once that mode exists, with its own service reading the same
key) keeps grblHAL down; grbl, unset, or a missing config starts it.
Board-verified both ways: cloud in the conf leaves the controller
stopped with a clear message, grbl starts and serves normally.
