Weather-Widget: replace drop-down selectors with scrollable rows (#253)

* adding details bar with icons and animations * adding lazy-rows, again * adding switch for compact mode / adjust padding * corner adjustments * Adjust alignment and typography * [Fix] Add missing outlineVariant to platform material3 dynamic color schemes * Adjust colors * Increase icon weight * Increase time selector touch target size * Change divider color * Adjust selection highlight color * add checks for valid details / display location icon on lat-lon location * removing redundant check for valid precipitation * Add colors argument to weather icons * Add Blend from material-color-utilities library * Blend weather icon colors towards theme color * Remove C/F * Add item blending when scrolling into / out of view * Create :ui:ktx:LazyListLayoutInfo.kt / increase provider padding --------- Co-authored-by: MM20 <15646950+MM2-0@users.noreply.github.com>
