Fresh-install bug report fixes:
- 'Master Site' button error 'app.modal.show is not a function': the
multi-site status modal used the legacy app.modal.show() signature; the app
exposes app.modal.open({title, bodyHtml, size}). The site-status request
itself worked -- only the rendering call was wrong.
- Agents with no discovery yet showed a fake 'v2.0.0' (three hardcoded
fallbacks). Now 'unknown', so a host whose agent never connected isn't
presented as an old version.
- The default org name (browser tab title) is set by theta-suite's setup.sh;
that default is fixed separately there (CFG_ORG -> Theta Directory).
