Query images attached to a retrieval test vanished as soon as the run's
history record was selected, and were never shown again after a reload,
because nothing persisted them: the gateway dropped `queryImages` when writing
`answer_traces`, the console trace/research responses had no image field, and
the composer cleared its images on every record selection.
- knowledge-fs: add a nullable JSON `query_images` column to `answer_traces`
(migration 0049 for postgres and tidb), persist and read it in the answer
trace repository, and expose `queryImages` on quality trace list items.
- api: enrich trace and research task responses with
`KnowledgeFSQueryImageResponse`, resolving file names and short-lived signed
preview URLs only for files the acting account still owns; regenerate the
console and service contracts.
- web: keep composer images scoped to the selected record like the query
text, remember images per run in this session, fall back to persisted
previews (with a labelled placeholder when the file is gone), show them in
the result panel and as a count on history records, and carry them into
retests.

Bring the LLM-driven "automatic" metadata filtering mode from the legacy
Knowledge Retrieval node to the KnowledgeFS retrieval node
(knowledge-retrieval-v2).
Backend:
- Accept `automatic` in `metadata_filtering_mode` and add
`metadata_model_config` to the node entity.
- Add `automatic_metadata_filter.py`, which reuses the legacy metadata
filter prompt templates, invokes the configured model, parses the JSON
answer and normalises operators/values against the KnowledgeFS
metadata catalog before building custom metadata conditions.
- Resolve the shared metadata catalog across the selected spaces through
the new `list_metadata_fields` app execution capability (paginated),
fail closed on missing/unavailable models and catalog admission errors,
fail open on extraction errors, and expose the outcome via
`metrics.metadata_filtering` and `llm_usage`.
- Inject the default extractor from the node factory.
- Fix an unescaped brace in the legacy completion prompt template that
broke `.format()`.
Frontend:
- Offer disabled/automatic/manual modes, normalise unknown persisted
modes to disabled, store the automatic model and completion params,
render the model selector through the shared MetadataFilter, and
require a model when saving in automatic mode.
