fix: Dice So Nice import v14 compat, override Foundry text colors for readability

- hooks.mjs: replace static dice-so-nice import with dynamic import
  using game.modules.get('dice-so-nice').id (path removed in v14)
- hooks.mjs: fix permission condition (|| -> &&), jQuery -> vanilla JS
- less/base.less: override --color-text-* and --button-text-color
  for both .themed.theme-dark (AppV2) and body.theme-dark (legacy apps)
- target #settings-config buttons + labels + hints for dark grays
