For the static page an error message displays stating no room
was specified. On mobile for unsupported browsers, the dial in
info will not show.

- Move the existing components for the static dial in page into
  a separate folder for easier reuse.
- Reuse those components for displaying dial-on numbers on the
  mobile page for unsupported browsers.
- Modify those components to support having tel protocol
  links on the dial-in numbers.
- Have DialInSummary, formerly DialInInfoPage, respect a
  passed in className prop for easier styling differences.

* feat(info): new dialog design

- Add display of a dial in number.
- Add a static page to show a full list of dial in numbers.
- Add password management.
- Invite modal will be changed soon to remove password and
  dial-in.
