Create Embeddings for field(s) Supabase DB

Generates and stores vector embeddings for specified fields in a Supabase database table. Accepts structured data objects, a list of fields to embed, and table details as input, then returns the stored objects with new embedding columns. The tool uses OpenAI's API to create embeddings for each specified field (e.g., food name and summary), appends these as new columns, and inserts the enriched objects into the Supabase table.
