Pull request overview

Adds the missing “Cumulative production” (1505) sensor to Indevolt Gen-2 devices so it is created and polled like it already is for Gen-1, and updates the sensor snapshot expectations accordingly.

Changes:

• Expose the cumulative_production sensor (1505) for Gen-2 by removing the Gen-1-only restriction in the sensor description.
• Ensure Gen-2 polling requests key 1505 by adding it to the Gen-2 SENSOR_KEYS list.
• Update sensor snapshot tests to include the new Gen-2 entity.
