Subject: [PATCH] Add running_productions_quantity to ProductionPlan:
 Introduced a new field to track the quantity of ongoing productions. Updated
 the DirectorWorker to parse this new field from the database and adjusted the
 free capacity calculation accordingly. Enhanced logging to provide detailed
 information when production cannot be started due to capacity constraints.
