gdb: Improve debug scripts organization and output

Enhance debugging scripts with the following improvements:
- Show backtraces for all threads during hard fault (not just current thread)
- Clean up capture_race_state.gdb formatting and variable naming
- Add GDB UI settings to combined_debug.gdb for better readability
  - Display only basename for files
  - Disable pagination
  - Enable pretty printing
- Improve timestamp logging format in race condition debugging
- Clean up comments and standardize debug message formatting

The changes make debugging output more comprehensive and consistent.
