Fix event data variables for time_pattern triggers

Added guards to event data variables (event_hub_name, event_album_name,
etc.) to check if trigger.event is defined before accessing it.

Previously, these variables would error when the trigger was time_pattern
(hourly_timer) since trigger.event doesn't exist for non-event triggers,
causing the entire automation to fail silently.
