Polish: smaller version text, bigger loader logo, keep RevealJS slide on recompile

- Reduce the dashboard instance-name/version font size (07 -> 06).
- Enlarge the Verso logo in the loading animation (160px -> 240px).
- Preserve the current RevealJS slide across recompiles: capture the deck's
  URL hash (same-origin) and re-append it to the iframe src so the new build
  reopens on the same slide instead of jumping to the start.
