Fill five version gaps from #30

- World age on 1.21.11: World.getTime() was a shortcut for
  getLevelProperties().getTime(), which every version has, so
  getWorldAge uses that everywhere (the TPS feature and day counter got 0
  on 1.21.11).
- Screen resize on 1.21.11: override resize(int, int), the new signature.
- Splash loading-bar border on 1.21.9+: drawBorder was renamed
  drawStrokedRectangle.
- Drag deltas on 1.21.9+: mouseDragged(Click, offsetX, offsetY) gets the
  deltas as offsetX/offsetY; Saturn's screens got 0.0 before.
- Role icon in player names on 1.21.4-1.21.7: only storing the player in
  the render state needs Fabric API's render state data (1.21.8+). The
  updateRenderState hook now runs on every version and only the setData
  call is limited to 1.21.8+.
