🐛 fix: Wizard — hostname editovateľný, resources v 3 krokoch, oprava pomlčky

- Krok 1: Názov kontajnera (zobrazenie v Proxmoxe)
- Krok 2: Hostname (editovateľný, predvyplnený z názvu)
- Krok 3: IP + gateway
- Krok 4: DNS
- Krok 5: Disk
- Krok 6: RAM
- Krok 7: CPU
- Krok 8: Užívatelia
- Krok 9: Potvrdenie
- Oprava trailing pomlčky v hostname (sed orezanie)
