IPAM: Hierarkkinen puunäkymä + VLANit erilleen

- Subnetit ja IP:t näytetään hierarkkisena puuna jossa pienemmät
  verkot menevät isomman sisään (esim. /24 → /16 → /8)
- Expand/collapse klikkaamalla ▶/▼ ikonia
- Drill-down: poraudu verkon sisään → -nuolella, breadcrumb ylhäällä
- VLANit erotettu omaksi luetteloksi verkkojen alapuolelle
- Omat "Lisää verkko/IP" ja "Lisää VLAN" -napit
