[TFS1.4] Teleportation System for Trade Center with Entry and Exit Portals

[srunobantana]

Note: ChatGPT was used to format and optimize the code, as well as to add prints and comments in both Portuguese (my language) and English (forum language). Apologies for the large code; feel free to delete what you don't need.

About: The player enters the portal and will always return to the point of origin. You can place one portal in each city to teleport the player to the DP Central, Trade Center, or PvP Center. The player will always return to where they came from.

UPDATE: The code has been modified to ensure it returns to the correct position. Comments in both English and Portuguese have been removed for clarity, and print statements have been commented out.
