refactor: split large page components + taxonomy/HeatBadge/FutureAvailability improvements

- Taxonomy: merge VERIFIED_PORTFOLIO + EXTERNAL_MARKET display → 'Plattform' (dark blue) across all surfaces
- HeatBadge: new flame indicator for hot properties (grid, list, pipeline views)
- FutureAvailabilityContextPanel: richer detail page with AI summary, strategic assessment, sources
- Refactor Pipeline.tsx (630→152 lines) → pipeline/PipelineCard, PipelineColumn, PipelineDetailPanel, pipelineConstants, pipelineUtils
- Refactor IntelligenceMatchCard.tsx (483→179 lines) → FutureAvailabilityCard extracted
- Refactor MatchDetail.tsx (559→464 lines) → useMatchDetailData hook, MatchDetailPropertyDetails
- Refactor Compare.tsx (638→485 lines) → compareUtils, CompareCriteriaCard extracted
