feat(bedwars): show username to self

This pull request updates the chat and join message handling in the BedWars game, particularly during the waiting phase before a game starts. The changes improve how player messages and join notifications are displayed to enhance the lobby experience and maintain anonymity before the game begins.

Lobby chat and join message improvements:

• Players in the waiting lobby now have their chat messages formatted with their rank prefix and appropriate text color, and messages are broadcast to all lobby players.
• When a player joins during the waiting phase, their join message uses a random string as their display name for other players, and their own display name is set to this random string, preserving anonymity before the game starts.

Code maintenance:

• Imported the GameStatus enum in ActionPlayerChat.java to support the new lobby chat logic.
