Implement notifications cron endpoint (P2.5)

Add daily email notification system that sends training decisions
at each user's preferred time in their timezone.

Features:
- Timezone-aware notification matching using Intl.DateTimeFormat
- DailyLog-based notifications with duplicate prevention
- Nutrition guidance integration via getNutritionGuidance
- Graceful error handling (continues processing on per-user failures)
- Summary response with detailed stats

Includes 20 tests covering:
- CRON_SECRET authentication
- Timezone matching (UTC and America/New_York)
- DailyLog existence and already-sent checks
- Email content assembly
- Error handling and response format

### P2.5: POST /api/cron/notifications Implementation ✅ COMPLETE
- [x] Send daily email notifications at user's preferred time
- **Files:**
- `src/app/api/cron/notifications/route.ts` - Find users by hour, compute decision, send email
- `src/app/api/cron/notifications/route.ts` - Timezone-aware user matching, DailyLog fallback, email sending
- **Tests:**
- `src/app/api/cron/notifications/route.test.ts` - Test timezone handling, duplicate prevention
- `src/app/api/cron/notifications/route.test.ts` - 20 tests covering timezone matching, DailyLog handling, email sending
- **Features Implemented:**
- Timezone-aware notification matching (finds users whose notificationTime matches current hour in their timezone)
- DailyLog-based notifications with fallback to real-time calculation when DailyLog missing
- Duplicate prevention (only sends once per user per hour)
- Nutrition guidance integration (seeds, carbs, keto)
- CRON_SECRET authentication
- Returns summary with emailsSent count and timestamp
- **Why:** Email notifications are a key feature per spec
- **Depends On:** P2.4
