feedback7 G-UI: reselecting the same operator keeps its draft skill and module (PR #306 by @Xinglan233)

Applied as-is. Clicking the operator already in the 自选 draft no longer rebuilds the draft from the saved pick or the default, so an in-progress skill or module edit stays. Choosing a different operator still loads that operator's saved pick or defaultPick.

Tests: node --test test/ui/diy-ui.test.js test/ui/feedback5-module-trait.test.js test/ui/diy.e2e.test.js — 25 pass, 0 fail. The diy.e2e suites skipped because SP_E2E is unset.
