Refactored Mudlet GUI and Mapper configuration sending

Added:
  - sendMudletMapperInstall function to handle mapper package
installation via Client.GUI

Changed:
  - Reordered GMCP messages to send Client.Map before Client.GUI for
proper Mudlet client
  handling
  - Refactored sendMudletConfig to use dedicated functions instead of
inline payload
  creation

Removed:
  - Unnecessary user record fetch in sendMudletConfig function
  - Duplicate payload construction for mapper installation
