Fix installation issue with missing server.js

Fixed a critical installation issue where server.js and server-endpoints.js were not being
copied to the install directory. This caused the service to fail with 'Cannot find module'
errors when trying to start.

Changes:
- Updated copy_module_files in file-creator-module.sh to also copy main server files
- Added error handling if server.js is missing
- Added better logging during file copying
