refactor(restart): replace std::runtime_error with WARNING_QUIT

Replace standard exception handling with project-specific error handling
in restart.cpp to comply with cpp-code-style skill guidelines.

Changes:
- Replace 4 instances of 'throw std::runtime_error' with ModuleBase::WARNING_QUIT
  in functions: write_file2() and read_file2()
- Remove unnecessary #include <stdexcept>
- Add #include "source_base/tool_quit.h"

This follows the ABACUS code style rule that requires using
ModuleBase::WARNING/WARNING_QUIT instead of standard exceptions.
