feat(vertrieb): Lead-CRM mit Dossiers, Kontakten & Austausch-Log

Neues Lead-Modul im Vertriebsbereich: qualitative Dossiers (Stammdaten,
Pain & Bedarf, Soft Factors, Strategie), Kontaktpersonen, Austausch-Log
mit Follow-up-Daten und Lead→Deal-Promotion. Routen /leads (Liste, nach
Status gruppiert) und /lead/:id (Dossier), Teaser im Bereich Vertrieb.

Migration 0008_lead_crm (lead, lead_contact, lead_touchpoint).
Datenmodell-Tabellen liegen in der gemeinsamen schema.ts (Folge-Commit).
