Electronics Catalog: API, MCP server, frontend and deployment

Verified catalogue of mobiles and laptops sold in India, collected from
real retail listings (FastAPI backend, React frontend, Postgres/pgvector).

- REST API under /api/elec (read-only catalogue; admin endpoints need login)
- MCP server (FastMCP) at /mcp/ with list_categories, search_products,
  get_product and price_history tools
- Real ratings and reviews read from product pages and search results
- Production Dockerfile (requirements-api.txt, no PyTorch) and
  .env.production.example; remote database only via an explicit
  ELEC_ALLOW_REMOTE_DB host/name allowlist
- docs/API.md: endpoint and MCP reference with live examples
