feat: Add 76 Level-2 regex checks for document correctness verification
Split dsi_document_checker.py (466 LOC) into doc_checks/ package (9 files).
Two-pass L1→L2 logic: L1 checks "Is it mentioned?", L2 checks "Is it correct?"
(e.g. controller has full address, specific Art. 6 lit., concrete time periods).
138 total checks (62 L1 + 76 L2) across 7 doc types:
- DSE Art. 13: 31, Impressum §5 TMG: 16, Cookie §25 TDDDG: 15
- Widerruf §355: 15, AGB §305ff: 21, Social Media Art. 26: 20, DSFA Art. 35: 18
Frontend: hierarchical L1→L2 display with dual progress bars
(green=completeness, blue=correctness).
