feat: Tender-Analyse Pipeline — Upload, Extraction, Control-Matching

Phase 3 des Payment Compliance Moduls:
1. Backend: Tender Upload + LLM Requirement Extraction + Control Matching
   - DB Migration 025 (tender_analyses Tabelle)
   - TenderHandlers: Upload, Extract, Match, List, Get (5 Endpoints)
   - LLM-Extraktion via Anthropic API mit Keyword-Fallback
   - Control-Matching mit Domain-Bonus + Keyword-Overlap Relevance
2. Frontend: Dritter Tab "Ausschreibung" in /sdk/payment-compliance
   - PDF/TXT/Word Upload mit Drag-Area
   - Automatische Analyse-Pipeline (Upload → Extract → Match)
   - Ergebnis-Dashboard: Abgedeckt/Teilweise/Luecken
   - Requirement-by-Requirement Matching mit Control-IDs + Relevanz%
   - Gap-Beschreibung fuer nicht-gematchte Requirements
   - Analyse-Historie mit Klick-to-Detail
