Pull each individual's highlighted media image via webtrees'
Individual::findHighlightedMediaFile, attach as Symfony inline
parts with stable cid:avatar-<xref> identifiers, and render
border-radius:50% on the <img>. Couples on anniversaries show
both spouses' circles side-by-side.
Fallback when no image is available (privacy-hidden record, no
OBJE, external URL, unreadable file): a CSS-only coloured circle
with the person's initials. The hue is derived from a hash of
the XREF so the same person keeps the same colour across
newsletters.
Done via a NewsletterMailer subclass of EmailService that adds a
sendWithEmbeds() method — the parent's transport() and DKIM
config still apply, only the message-construction path differs.
