Today I updated the ALS_WARM node to implement the check of the ALS source being off at WEB: it checks if ALS_WEB_PD_GREEN_MONI_CALI is above a threshold (green_moni_thr = 30) and if ALS_WEB_PSTAB_SAFETY is equal to 1. In case any of those happens between the SCAN state and the LOCKED_BEATING_ON one, the node will jump to the ALS_FAULT state, where the same commands as in DOWN are done, and then the node cannot move out of it by itself without a manual intervention (this behaviour mirrors what happens in the INJ_MAIN node), so blocking the lock acquisition of ALS and preventing the false positives we've been seeing lately. In the DOWN and OFFLOADED_TO_MANAGER states the check does not happen.

I will keep this only in the West ALS node for a little time to onitor it, then I will implement it also in the North ALS node. The new states layout is attached.
