feat(agent): PreScanWizard im ComplianceCheckTab (P79 sichtbar)

Wizard war bisher nur im DocCheckTab eingebaut, der aber nirgends im UI
gemountet ist. Daher: alle Compliance-Checks schickten scan_context=null,
P72 Branchen-Filter wirkte nie.

Fix: PreScanWizard ins ComplianceCheckTab über die Document-Rows
gestellt. Submit-Button disabled bis alle 8 Felder (Branche, B2B/B2C,
Direkt-Vertrieb, Rechtsform, Konzern, MA, Besondere Daten, Drittland)
gesetzt sind. scan_context wird im POST body mitgesendet.
