fix(ui): neutralise dark theme — eliminate blue-shifted grays across all surfaces

Replace blue-shifted CSS variable values with balanced neutral RGB, add
comprehensive dark-mode overrides for bg-gray-*, border-gray-*, text-gray-*,
and their dark: variant forms. Remove light-mode text/border overrides that
leaked into both modes. Replace hardcoded rgba(255,255,255,...) in component
classes with CSS variable references. Merge duplicate fadeSlideIn keyframe
into fadeSlideUp. Change .app-data-table overflow to clip for sticky compat.
