Add enhanced sleep data extraction with new fields

- Update Sleep model with new columns: body_battery_change, skin_temp_celsius, awake_count, sleep_quality_score, sleep_recovery_score, spo2_avg, spo2_min, respiratory_rate
- Extend GarminSleepData schema with field mappings for all new metrics including body battery changes, skin temperature, awakening counts, sleep quality scores, SpO2 data, and respiratory rate
- Update extract_sleep_data function to save new fields to database
- Remove unused alembic directory since project uses direct SQLAlchemy table creation
