fix: close missing > on Joomla-exported [Poster](</images/...) attachment links (#81)

The Joomla export wrote markdown links with an angle-bracket-wrapped URL
that's missing its closing >, e.g. `[Poster](</images/foo.png)`. Marked
silently treats those as a link with literal text, so the Poster anchor
on community/events rendered as a non-link (the symptom reported in #81).
Add the closing > and also copy the four event posters plus the
Biocuration 2025 poster into public/images so the URLs resolve on beta
without depending on reactome.org.
