refactor(gui): refactor draw_hotkeys to improve code health (#86)

- Break down the monolithic `draw_hotkeys` method into smaller,
  focused component functions: `draw_hotkeys_header`,
  `draw_hotkeys_search`, `draw_hotkeys_table`, and
  `handle_hotkey_action`.
- Improve readability and maintainability of the `src/gui/draw.rs` file
  while preserving identical behavior.
