feat(sdk): Logo-Navigation, stabile Versionsnummer V001 + Firmenname im Header

- Logo-Klick fuehrt zurueck zur Startseite (Neues/Bestehendes Projekt)
- Neue projectVersion im SDK State (inkrementiert nur bei explizitem Speichern)
- Header zeigt Firmenname + V001-Format statt auto-inkrementierende Sync-Version
- Sidebar Logo von Link auf Button umgestellt mit customerType-Reset
