refactor(theme-studio): drop the orphaned dropdownRowTextColor helper

dropdownRowTextColor was exported and unit-tested but had no runtime caller: it
computed text color for a vertical-list dropdown row, a UI replaced by the swatch
gallery popup (colored buttons, no per-row text), so its regression rationale is
moot. Remove the function, its export, and its four tests; regenerate the page
(theme-studio.html staged so check-generated stays green).
