The Pro/embedded composer-hoisting effect built its own `replyTo`
straight from `selectedEmail`, unconditionally, ignoring
`pendingDraft.replyTo`. That meant intent set by the opener - e.g.
handleForwardAsAttachment's synthetic message/rfc822 attachment -
would silently get dropped when the composer is hoisted into a Pro
tab, falling back to a normal quoted forward instead. Mirror the same
precedence the non-embedded render path already uses just below
(`pendingDraft.replyTo` wins when set).
