llama_parse FRs now emit the standard raw_lines/txn_blocks/txn_dicts events,
so remove the special-cased step from SSEEventStep and stepper progress calc.
- Detail page: red Delete button beside Retry (disabled while processing or
in-flight), confirm dialog, toast feedback, navigates back to the list
- List rows: per-card delete IconButton with stopPropagation, disabled while
processing; reloads after success
- Backend cascades linked expenses + ambiguities and evicts the expenses
response cache on delete
- 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.
