feat: Pipeline↔Anfragen integration + Compare→Pipeline + KI stage detection

Navigation: Deal Pipeline moved after Vergleich (before Anfragen)

Compare → Pipeline:
- Bookmark icon per column header; BookmarkCheck when already in pipeline
- Passes propertyId, propertyAddress, area/rent labels on save

Pipeline cards now unit-level:
- propertyAddress shown with MapPin on every card
- Chat icon (MessageSquare) on cards with linked inquiry → navigates to /demand/anfragen?inquiry=xxx
- Detail panel: Chat chip links to specific inquiry thread, propertyAddress displayed

Anfragen → Pipeline KI detection:
- Keyword scan on every sent message (besichtigung → VISITED, mietvertrag → NEGOTIATION, unterschrieben → CLOSED_WON)
- Only advances stage, never goes back
- Purple KI alert banner with direct Pipeline link, auto-dismisses after 6s
- Pipeline badge in inquiry list + stage chip in chat header with nav link
- URL param ?inquiry=xxx pre-selects inquiry (used from Pipeline chat button)

Domain: PipelineItem gains propertyId, unitId, propertyAddress, inquiryId
Mock data: pl-001/pl-002/pl-004 linked to inq-001/inq-005/inq-004
