- Add BlockSnapshot Prisma model (html, css, version, changelog) + migration
- Add API endpoints: POST/GET /blocks/snapshots, GET /blocks/snapshots/:id
- BlockMetaBar: version dropdown, HTML capture on save, onSnapshotSelect prop
- "Сохранить версию" now captures innerHTML snapshot + CSS and stores in DB
- Selecting archived version shows stored HTML snapshot instead of live component
- Yellow banner "Архивная версия" with link to return to current
- Split all 8 block pages into Server Component (metadata) + Client Component
- Add data-block-capture attribute for snapshot capture targeting
