Jyong 57d03faa98 fix(workflow): let the KnowledgeFS retrieval node run on text or image alone
The KnowledgeFS retrieval node treated the query text as mandatory even though
a query image is a complete input on its own. Text and image are now
alternatives: the node needs at least one of them, never both.

- web: drop the required mark from the query text field; the checklist fails
  only when neither variable is bound (new i18n message in every locale).
- api: make `query_variable_selector` optional with a model-level rule that
  one of the two selectors must be set, and only map the query variable when
  it is bound. At runtime an empty text without images is a configuration
  error; an image-only query retrieves with an empty text, merges spaces on
  their own scores instead of a text reranker, skips automatic metadata
  extraction, and skips the text-based failed-query capture.
