UI update & fix some bug

 - Added a BOOST button in the top-right corner (above the stratosphere) with the same effect as the space bar. Supports both mouse and touch.

  - Added red guide lines on the left and right sides of columns to indicate which column is being dragged.

  - Reorganized the x1 / x2... display during launch into a temporary display system, now showing for a set duration before disappearing.

  - Implemented fixes to reduce cases where ground matches unnaturally connect to mid-air clusters and cause re-launches.

  - Improved block state detection near the stratosphere to enhance behavior stability.

  - (Multiplayer) Improved tracking and update processing for the player list.
