Preview Email v3.0.4

Pre-release of v3.0.4 for testing ahead of the formal release.

Added

• Opt-in HTML (Exact) preview of the Order Confirmation. It renders the email by running the store's own order::send_order_email() for a recent order and capturing exactly what it would send -- no mail is sent. It reflects customizations in that code; product rows come from core's own order::buildProductOrderedEmailStrings() where available (zencart/zencart#8015), the stock layout otherwise. The standard preview, and every other email, are unchanged; the exact view is a separate button you press when you want it.

Fixed

• Previews are no longer addressed to One Page Checkout's guest placeholder (blank-email customer).

The formal (non pre-release) build and the Plugins Library update follow once the core PR (zencart/zencart#8015) is settled.
