feat(ui): dual market score methodology page and translations
Task 7: update market_score.html + en/de translation keys for the
Marktreife-Score / Marktpotenzial-Score dual score system.
Changes:
- market_score.html: add Two Scores intro section (blue gradient card),
Marktpotenzial-Score component cards (5 components), score bands for
opportunity score, extend FAQ loop from 5 → 7 entries, add q6/q7
to JSON-LD FAQPage structured data
- en.json: rename existing headings to Marktreife-Score prefix; add 30
new mscore_dual_* / mscore_reife_* / mscore_potenzial_* / mscore_pot_*
keys for dual score UI and FAQ q6/q7
- de.json: same 30 new keys in native German (linguistic mediation,
not word-for-word translation); update renamed heading keys
