PhoenixKit V13 Migration: Enhanced Email Tracking with AWS SES Integration

This migration enhances the email tracking system to support comprehensive
AWS SES event types and improved message ID synchronization.

## Changes

### Email Log Enhancements
- Adds aws_message_id column for improved AWS SES message correlation
- Adds timestamp columns for detailed event tracking (bounced_at, complained_at, opened_at, clicked_at)
- Expands status enum to include all AWS SES event types
- Adds partial unique index on aws_message_id for duplicate prevention (only for non-NULL values)

### Email Event Enhancements
- Adds support for reject, delivery_delay, subscription, and rendering_failure events
- Adds specific fields for new event types (reject_reason, delay_type, subscription_type, failure_reason)
- Expands event_type enum validation

### New Event Types Supported
- **reject**: Email rejected by SES before sending
- **delivery_delay**: Temporary delivery delays
- **subscription**: List subscription/unsubscription events
- **rendering_failure**: Template rendering failures

### New Status Types
- **rejected**: Email rejected by SES
- **delayed**: Email delivery temporarily delayed
- **hard_bounced**: Permanent bounce (non-recoverable)
- **soft_bounced**: Temporary bounce (recoverable)
- **complaint**: Spam complaint received

## PostgreSQL Support
- Supports PostgreSQL prefix for schema isolation
- Uses proper timestamp types for event tracking
- Adds necessary constraints for data integrity
- Backward compatible with existing data
