Add on-screen feedback for the Shift copy-settings gesture, driven by a single configurable color (visuals.toml [overlays].copy_config): - eligible-target tint over every same-type building/site while a config is cached (source included), shown only while a paste is possible; - a brief selection-style outline flash on copy (source) and paste (target). Flashes use a wall-clock countdown (frame delta), so they play for a fixed 0.3 s regardless of game speed and while paused, and fade independently per building. Extract the footprint-rect resolution shared by the selection highlight and the new feedback into footprintWidgetRect(). Pure rendering; no simulation or selection state touched.
