Refactor Tesla charging templates to modern template syntax

- Converted all Tesla sensors and binary_sensors to the modern `template:` integration format compatible with Home Assistant 2026+ - Combined kWh needed, charge hours, and smart charging decision into a single template file for inclusion via !include_dir_merge_named - Preserves existing behavior while preparing for future HA versions - Legacy template warnings remain for binary_sensor but functionality works
