Linus Rath 034ee27057 fix: keep the setup token out of access logs, referers and history
The startup banner printed `/setup?token=...`, so the one-hour bootstrap
token that grants the setup wizard landed in reverse-proxy access logs,
Referer headers and browser history. The link now carries the token in
the fragment, which never leaves the browser, and the wizard removes it
from the address bar as soon as it reads it. Old `?token=` links still
work and are cleaned up the same way.

/**
* The setup link printed at startup carries the token in the fragment
* (`/setup#token=...`): a fragment never reaches the server, a reverse
* proxy's access log or a Referer. Older logs printed `?token=`, which is
* still accepted. Either way the token is removed from the address bar (and
* so from history) as soon as it is read.
