Refactor setButtonLabels() to use std::vector for safer memory management

Browse Source 
- Replaced manual dynamic memory allocation with std::vector in
  setButtonLabels(const button_label*...) and setButtonLabels(const std::vector<button_label_cc>&...).
- Reserved vector capacity upfront to match label_count, optimizing memory usage.
- Improved safety and readability by removing manual delete[] calls and
  handling memory cleanup through vector's automatic management.
