Update Home Assistant configuration and automations

- Updated .ha_run.lock to reflect the new Home Assistant version 2026.4.2.
- Enhanced automations.yaml with improved entity targeting and additional automation actions for window shading.
- Refactored configuration.yaml to include templates from a separate file for better organization.
- Added new ESPHome configurations for window sensors and updated KNX configurations for door contacts and buttons.
- Removed deprecated pv_to_dhw.yaml package to streamline the project.
