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"
Implement three core blueprints using convention-based entity lookup:
- apply_lighting_mode: Dynamic mode application with behavior polymorphism
- weekend_mode_schedule: Auto-enable/disable based on day of week
- weekend_mode_apply_settings: Apply AL adjustments for weekends
Blueprints use convention over configuration, allowing unlimited custom
modes without code changes. Modes discovered via naming pattern:
input_text.adaptive_lighting_settings_{{mode}}
