docs: upgrade all docs pages with Mintlify premium components (#642)

Replace plain markdown lists, tables, and numbered steps with interactive
Mintlify v3 MDX components across all 50+ documentation files:

- Tabs: provider/parser/method selection guides, citation formats, component details
- Steps: setup flows, pipeline stages, connection initialization
- CardGroup/Card: feature overviews, "what you get" sections, navigation footers
- AccordionGroup: FAQ entries
- Check/Warning/Tip/Note/Info: callouts replacing plain bold text and inline notes

Files improved span the full docs surface: reference modules (context, llms,
kg, reasoning, embeddings, deduplication, provenance, parse, ontology, core,
semantic_extract), integrations (agno, docling, snowflake), graph/vector
store backends (apache_age, pgvector), and top-level guides (contributing,
governance, glossary, citation, community-projects, learning-more).
