### What changes were proposed in this PR? An operator is configured by a form, and the form is generated from the descriptor's own annotations. The same annotations are enough to fill it without a human: an enum offers its constants, a column knob takes a column of the type its rule allows, a numeric knob its declared bounds, and a conditional field is filled only where the branch that shows it is taken. This is one file because it is one decision made repeatedly — what a knob may hold — and splitting it would put half of that decision on either side of a boundary. `@SampleColumn` names the column a knob means where a type cannot say it: the opening price among four numbers, the country code among several strings. ### Any related issues, documentation, discussions? Part of #8325, 7 of 15. It builds on #8327, which adds the trait and the translator, and on the verification pieces before it; each is sized to be read in one sitting rather than landing as one diff. ### How was this PR tested? The tests in this change cover it. The whole set is exercised together once the last piece lands: every operator run through the engine and through its generated script, and the two answers compared. ### Was this PR authored or co-authored using generative AI tooling?
