fix: Raise full_text limit 10K→50K + combine all DSI texts for checks

Two fixes:
1. consent-tester: full_text truncation raised from 10,000 to 50,000 chars
   (IHK Internetangebot has ~50K chars, Beschwerderecht was after 10K cutoff)
2. Backend: dse_text now combines Playwright HTML + ALL DSI discovery texts
   for mandatory content checking. Previously only used first 8K chars from
   one source, missing Verantwortlicher/DSB that were in DSI documents.
