Add data-driven blueprint architecture for adaptive lighting modes

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}}
