Add centralized errorFormatter to convert various error types into readable messages, and apply it across edge functions. Replace String(error) usage with formatEdgeError, update relevant imports, fix a throw to use toError, and enhance logger to log formatted errors. Includes new errorFormatter.ts and widespread updates to 18+ edge functions plus logger integration.
