fix: Compare→Pipeline flow, pipeline card navigation, remove floating AI button

- Remove CompareTray fixed bottom bar; replace with compare count badge on Vergleich nav item
- Pipeline cards redesigned to match search result card visual style (MatchScoreDisplay, type chip, stage chip, MapPin layout)
- CompareColumnHeader: redesigned with proper Details/Merken action buttons, clickable title
- AddToPipelineDialog now mounted on Compare page (was missing — bookmark had no effect)
- Pipeline card ExternalLink icon navigates to property detail page; detailPath prefers stable propertyId over volatile session matchId
- Add matchId field to PipelineItem domain; pipelineStore stores it on save
- All 8 mock pipeline items now have propertyId for reliable cross-session navigation
- Remove GlobalAIAssistantButton floating overlay (was blocking form submissions and clicks)
