Merge origin/develop into feat/no-code-cms

Bring CMS/event branch up to date with develop. Net incoming change is the
CI deploy runner config (install rsync/openssh); all other develop history
was already present via shared kristijan-dev lineage.

Meet Student Slovenia 2026 remains on this branch only (unpublished).
