catborise 3a560e9f85 fix(console): a console that cannot open says why and starts no client
A stopped VM, an unreachable or unsupported console and a disabled serial
console rendered the lite VNC page under the error: it connected to novncd
anyway, showed "Something went wrong" and offered keys, Scale and Send
CtrlAltDel for a console that was not there. A refused console was a bare
text 403 inside the popup.

- console-error.html: the console shell with the VM's name and the reason,
  no menu and no script; a refused or unknown VM gets it with 403 and
  without the VM's name, as before for everyone (no superuser exception).
- The view signs the console token only for a page that connects.
- console-menu.html: the Send key(s) menu and Fullscreen, included by the
  console pages; the serial page lists only the keys it sends (the VNC
  groups did nothing there).
- Every console window is titled "<VM> - Console".
- The lite page no longer takes a VNC password from its link.
- The shell lost its 850px x 600px corner radius (a grey arc on the
  serial and error pages) and spans the window (container-fluid).
