✨ Added "Email" card for inserting content that only appears when emailing posts to members

no issue

- any content inside the email card will not appear on the site, instead it will only be shown when using the members system to email the post to your members
- can `{first_name}` or `{first_name, "fallback"}` to personalise the email content for each member
