Add use_entity_picture option to picture-entity card

Allow picture-entity cards to display the entity's entity_picture attribute instead of requiring a manually configured image URL. This is particularly useful for entities that dynamically set their entity_picture (e.g., update entities showing component logos, custom integrations, etc.).

The static image configuration remains as a fallback when the entity_picture attribute is not present or when use_entity_picture is not enabled.

Changes:
- Add use_entity_picture boolean option to PictureEntityCardConfig
- Implement logic to check entity_picture attribute when enabled
- Update validation to accept use_entity_picture as valid image source
- Add editor toggle with helper text
- Add translation strings for the new option
