ipn/localapi,client/web: clean up auth error handling

Browse Source

This commit makes two changes to the web client auth flow error
handling:

1. Properly passes back the error code from the noise request from
   the localapi. Previously we were using io.Copy, which was always
   setting a 200 response status code.
2. Clean up web client browser sessions on any /wait endpoint error.
   This avoids the user getting in a stuck state if something goes
   wrong with their auth path.
