FX.51 CivilCraft: Render view in 3D, and Apply / Close on the Sun menu

Owner request 2026-11-05. A Render button in the 3D bar draws the land as land: natural terrain colours (grass on the flat, earth and rock on the steep, lighter with height), sky and haze, filmic tone mapping, soft shadows from a default north-west sun (the Sun menu still wins when set). Does not change the model; remembered in the browser. The Sun menu gets Apply and Close buttons. Also: a Bootstrap tooltip shows the whole value of a number box too narrow for it. site-view3d.js, drive-ui.js, civilcraft.js; 3D suite 155/0. No visual check yet.
