Tracking lock state change events

The integration will emit a standardized event, regardless of the integration, called lock_code_manager_lock_state_changed. The format of the event data is as follows:

notification_source: event  # Can be event, state, or None
entity_id: lock_entity_id  # Entity ID of the lock that changed state
state: locked  # Current state of the lock
action_text: User code 2 unlock  # Optional text that the lock integration can provide that gives more context about what triggered the event
code_slot: 1  # Code slot that was used to affect the state of the lock. Can be 0 if there is no code slot to provide.
code_slot_name: my_name  # If a name was configured for a particular slot, it will be included here
from: unlocked  # previous state
to: locked  # new state
extra_data: ...  # If the event was triggered from a state change, the state object will be included here. If the event was triggered by an event in the lock's integration, the event data will be included here.
