feat: consult embeddings UI, vector search FLOAT32 fix, and base64 compartment decode

- Add Consult Embeddings sub-menu with chat-like Q&A interface
- Fix VECTOR_DISTANCE FLOAT32/FLOAT64 mismatch (array 'd' → 'f')
- Decode base64 compartment_id in _resolve_embed_config
- Sidebar sub-item navigation for Embeddings hierarchy
- Fallback to raw document display when no GenAI config available
