Update controller methods and fix const issues

Changes:
- Added stub implementations for Controller.cpp methods
- Fixed const issue in UserInterface methods (run, login, registerCustomer, handleOperation)
- Changed return types to use const pointers for read-only objects
- Updated maps and vectors to return const object pointers
- Fixed some function parameter names and signatures for consistency
