Content cleanup: fix unclosed tags, remove em/en dashes, verify translations

- Fixed 3 SI event posts that were missing their </article> and </main> tags
- Replaced all punctuation em-dashes and spaced en-dashes (435 across 64 files)
  with commas; normalized a SI date range to a hyphen to match EN/MK
- Verified the new Gallery + in-post gallery content is fully translated in
  EN/MK/SI (headings, titles, links, nav labels) with no English leftovers
