Fix checkout flow to redirect to specific order detail page

🔄 Better UX Flow:
- After successful payment: redirect to /orders/{order_id} instead of /access
- This shows the specific order details where users can see their purchase
- Users can then proceed to payment if needed or access their content

📧 Updated Shortcodes:
- {thank_you_page} now uses dynamic URL pattern: /orders/{order_id}
- {order_id} will be replaced with actual order ID by ShortcodeProcessor
- Added {thank_you_page} to order_created and payment_reminder templates

🎯 User Journey:
1. User receives email with payment link
2. After successful payment → redirected to specific order detail page
3. If not logged in → redirects to login, then back to order detail
4. Order detail page shows payment status and access information

Much better user experience than generic dashboard redirect!
