feat(fetch-requests): support llama_parse pipeline

- Fix PipelineType union: "llama_parser" → "llama_parse" (matches backend enum)
- Add "llama_extract" to SSEEventStep union
- PipelineStepper: advance Extract stage on llama_extract events

Dropdown/badge rendering is OpenAPI-spec-driven and picks the new value up
automatically; no other changes required.
