daemon: reload config before each token attempt

The daemon loaded config once at startup and held it in memory, so an
operator editing auth_code/refresh_token on the console (FTP) while it
ran was ignored. Re-read the disk config each ensure_token() so edits
take effect live without a plugin reload.
