Fix Authelia config path and stale schedule comments in conf templates

The Authelia config default pointed at /mnt/user/appdata/Authelia, which does
not exist — the auth stack lives in the Critical-Data share so it gets synced.
Because conf_populate only fills empty fields, that wrong non-empty default
blocked auto-detection permanently and left the auth page's rules panel dead.

Also corrects three schedule comments that no longer matched varaverk.cron and
two references to scripts that have since been renamed or split.
