init: clean history with no PII

Toto repo ma novou cistou historii (1 commit). Predchozi historie
byla smazana, protoze obsahovala osobni udaje (IP, emaily, hesla,
klice, tokeny, Volume cesty). Soubory v aktualnim commit uz tyto
udaje neobsahuji (nahradeno placeholdery <server-ip>, CHANGE_ME,
admin@example.com atd.).

Pokud chces zpet kompletni seznam starych commitu, mas je ve svem
lokalnim working tree - git log --all ukaze prazdno (protoze jsme
smazali .git/ a zacali znovu).
