release: 0.3.0: PTR fix via public resolvers; monitoring URLs and nav icons

panel: the PTR (reverse DNS) check no longer reports a correctly published
Fixed:
  - panel: the PTR (reverse DNS) check no longer reports a correctly published
Changed:
  - panel: the three monitoring pages now live at URLs that match their nav
  - panel: each entry in the navigation bar now carries an icon beside its label,
  - panel: the navigation bar is laid out as two rows on purpose — the signed-in

Full detail: CHANGELOG.md (0.3.0).
