fix: field normalization, AI connection validation, autofix filter (#581) (#638)

- Normalize name→nodeName and id→nodeId for node-targeting operations in
  the Zod schema transform, so LLMs using natural field names no longer
  get "Node not found" errors
- Replace hardcoded ALL_CONNECTION_TYPES with dynamic iteration so AI
  sub-nodes (ai_outputParser, ai_document, ai_textSplitter, etc.) are
  not flagged as disconnected during save
- Add .catchall() to workflowConnectionSchema and extend connection
  reference validation to cover all connection types, not just main
- Fix filterOperationsByFixes ID-vs-name mismatch: typeversion-upgrade
  operations now include nodeName alongside nodeId, and the filter checks
  both fields
