One-shot bilingual intro paragraph with markdown + author avatar

- Admin can set a per-locale intro paragraph for the next issue on
  the preferences page; cleared automatically after a successful
  send. Stored in module_setting (longText) so multi-paragraph
  notes fit.
- Intro is rendered via webtrees' CommonMark factory (same flavour
  as notes) with raw HTML escaped, supports {{first_name}},
  {{last_name}}, {{username}}, {{email}} substitution per recipient.
- Two-column intro layout: tree contact user's linked Individual
  becomes the editorial portrait on the left. Their avatar is
  added to the per-recipient embed set so the inline image always
  resolves rather than falling through to a tree-page login link.
- Masthead now shows the tree URL under the title.
- Avatar source dimensions bumped 96→192 px and JPEG quality 75→88
  so portraits stay crisp at retina display ratios.
