Problem: Segments crossing midnight were split into different nights
- 22:30-23:15 (21.03) → assigned to 21.03
- 00:30-02:45 (22.03) → assigned to 22.03
But both belong to the same night (21/22.03)!
Solution: Gap-based grouping
- Sort segments chronologically
- Group segments with gap < 2 hours
- Night date = wake_time.date() (last segment's end date)

Backend:
- New endpoint POST /api/sleep/import/apple-health
- Parses Apple Health sleep CSV format
- Maps German phase names (Kern→light, REM→rem, Tief→deep, Wach→awake)
- Aggregates segments by night (wake date)
- Stores raw segments in JSONB (sleep_segments)
- Does NOT overwrite manual entries (source='manual')
Frontend:
- Import button in SleepPage with file picker
- Progress indicator during import
- Success/error messages
- Auto-refresh after import
Documentation:
- Added architecture rules reference to CLAUDE.md
