License header standardization, copyright update and code beautification

License Changes:
- Add SPDX-FileCopyrightText identifiers for license compliance
- Update copyright years from 2024 to 2025
- Standardize copyright format with 'All rights reserved'
- Add complete GPL-2.0-only license headers to files missing them
- Ensure consistent license attribution across all source files

Code Beautification:
- Standardize indentation (convert tabs to spaces)
- Improve code formatting consistency
- Apply consistent style across C source files and Python scripts

Affects 53 files total: shell scripts, Python scripts, and C source files
