v1.5.0 - Control Sensors

New: Control Sensors

The "Schedule" settings are now called "Control" and include two new sensor options:

Block Sensor

• When this binary_sensor is OFF → switch is blocked (like time schedule)
• Works together with time schedule: both must allow it

Control Sensor

• Directly mirrors the switch: sensor ON → switch ON, sensor OFF → switch OFF
• Perfect for EPEX Spot or other dynamic tariff integrations

Both sensors are optional and can be combined with the existing time schedule.
