feat: score transparency on all cards + budget parser fix

- Single scoring system: MockupNeedProvider rewrites matches via calculateScore
  exclusively — allFactors always populated, no more dual-system (computeScore
  removed), weights from weightingProfile reflected in every breakdown
- ScoreInlineBreakdown: new component shows hard/soft criteria with importance
  labels (Entscheidend/Sehr wichtig/…) and formula on compact + expanded cards
- MatchCardAdapter: passes scoreBreakdown + allFactors to ViewModel
- MatchDetail: 'Zukunftssignal' label replaced with 'Future Availability'
- aiService budget parser: values < 100 treated as monthly and multiplied by 12
  to produce correct annual CHF/m²/year value — fixes 0-result searches
