Epic RPG: Party Hud

Fixed an issue where the tracker icon remained visible even when the teammate was in another dimension.

Added a system to clear old positions to prevent "ghost" data: if a player's position hasn't been received for a long time, their icon will automatically stop displaying.

The tracker now only shows members currently connected to the server, avoiding icons of players who have left the game or lost connection.

Improved the way the player's 3D position is converted to the 2D screen, using the same matrices and logic as the game itself. This makes the icon's position much more consistent and stable up close.

Fixed a bug where the party wouldn't load when entering another dimension.
