[KNOX-3506](https://issues.apache.org/jira/browse/KNOX-3506) - Knox default
login page flashes before modern login page displayed
## What changes were proposed in this pull request?
The login page painted the classic dark theme before the modern theme
applied. Root cause: a script-inserted `<link rel=stylesheet>` is not
render-blocking (only parser-created ones are), and the theme request was
queued behind jQuery.
- `login.html` — theme loader moved above jQuery (theme CSS requested at 15
ms instead of 1027 ms); document cloaked until the theme stylesheet resolves,
revealed on load/error/1.5 s timeout so a 404 or CSP block can never leave a
blank page.
- `knox.css / login.html / logout.jsp` — sign-in box centred in CSS instead
of by a jQuery setTimeout, removing a 74 px jump on first paint.
- modern/theme.css — button transition: all narrowed to the three properties
hover actually animates, so applying the theme no longer animates green→blue;
added missing sans-serif fallbacks to three Roboto declarations that otherwise
fell back to serif.
## How was this patch tested?
