fix: use environment MongoDB URI and update glossary slugs in PDF generator

- Changed hardcoded mongodb://localhost:27017 to use MONGODB_URI env var
- Added automatic database name extraction from URI or MONGODB_DB env
- Updated glossary slugs from long auto-generated to explicit frontmatter slugs:
  - tractatus-agentic-governance-system-glossary-of-terms → glossary
  - tractatus-agentic-governance-system-glossary-of-terms-deutsch → glossary-de
  - tractatus-agentic-governance-system-glossary-of-terms-franais → glossary-fr
- Enables PDF generation to work in production environment
