fix(agiloft): give natural language search a sentence that paints

check:canvas-sentences failed: the nlp_search card resolved to nothing on an
untouched canvas, so it painted empty. Its only basic-mode field was the
long-input query, and the field list is advanced, so every segment dropped.

The sentence now leads with the knowledge base, matching the shape List Tables
already uses — both operations are knowledge-base scoped rather than
table-scoped, so it also reads more accurately.
