Editorial redesign: event icons, timeline, person links

Reworks the newsletter as a family-chronicle layout: ivory paper
background, deep oxblood ink, aged-gold accents, EB Garamond
display with Georgia body fallback.

- Inline SVG event icons (sparkle for birth, dagger for death,
  interlocked rings for marriage). Falls back silently in
  Outlook desktop; modern Gmail / Apple / iOS / Outlook 365
  render them.
- Right-side gold hairline timeline running through the date
  column of every event row, with a filled dot per entry.
- Person names link to their webtrees Individual page via
  Individual::url() (absolute URL through route() → BASE_URL),
  including the avatar circles.
- German strings added for the new section kickers
  ("Family Chronicle", "Living kin who will celebrate this
  fortnight.", "Marriages still intact.").
