Fix blueprint input section structure to nest under blueprint key

Move input definitions from root level to be nested under the blueprint
section. Home Assistant requires input declarations to be under
blueprint.input, not at the root level.

This fixes import errors:
- "Missing input definition for adaptive_lighting_switch, led_color_entity, mode_input_select"
- "Missing input definition for sunrise_time, sunset_time, weekend_mode_boolean, adaptive_lighting_switch, max_brightness"
- "Missing input definition for toggle_time, weekend_mode_boolean"
