Stopping the server returned before the IRC listener's connections had
run their cleanup, and the database closed under them, so their
sessions, clients and channel memberships stayed and their nicks stayed
taken after a restart.
The IRC listener's stop now waits up to five seconds for every
connection's cleanup, which now runs on a context that stopping does
not cancel. The HTTP server's stop hook now runs Shutdown itself and
waits for it; httpServer is set before serving starts, and the server's
own signal watcher, which raced fx's stop hooks, is gone.

setupSPA took the file name from request.URL.Path[1:], which panics
when the path is empty, as it is for an absolute-form request line
with no path ("GET http://host HTTP/1.1"). It now trims a leading "/"
instead; an empty name fails to read, so the request gets the index
page, as "/" already does.
The new test in internal/server sends such a request and expects 200
and the index page. export_test.go gives it a Server whose router has
only the web client route.
