- Fix edit form pre-populating saved agenda using [value]+(input) binding

- Redesign meeting invite email: table-based layout, compact header, amber agenda
  box with numbered badges, two-column footer
- Fix stale email agenda bug: refresh entity after agenda save to bypass EclipseLink
  L1 identity map cache
- Remove permission wrapper from Election sidenav item; add routerLink to toolbar
