New "Drittlandtransfers" tab in the Vendor Compliance sidebar:
- Aggregates all vendor processing locations with non-EU countries
- Traffic light system: green (EU/adequacy), yellow (SCC exists),
red (no transfer mechanism)
- Stats cards: total, EU+adequate, third-country, action required
- Filter by status (all/OK/review/action required)
- Table with vendor name, country, mechanism, SCC status, TIA status
- "TIA erstellen" link to Document Generator for third-country vendors
- Help text explaining Schrems II / Art. 46 DSGVO requirements
Uses existing data model — no new API endpoints or DB tables needed:
- vendor_vendors.processingLocations (isEU, isAdequate)
- vendor_vendors.transferMechanisms
- vendor_contracts.documentType = 'SCC'
