feat(pitch-deck): AIPipeline slide numbers from pitch_pipeline_stats DB table

All KPI numbers on the AI Pipeline slide now load from the
pitch_pipeline_stats table via /api/pipeline-stats:
- Legal sources: 380+ (was hardcoded 75+)
- Unique controls: 25k+ (was 70k+)
- Obligations: 47k+ (from DB)
- EU regulations, DACH laws, frameworks: from DB
- Pipeline steps text: all counts dynamic

Numbers can be updated via SQL without code deploy:
UPDATE pitch_pipeline_stats SET value = X WHERE key = 'legal_sources';
