Apply clang-format to source files and fix linter config

- Formatted all .c/.cpp/.h files using LLVM style (4-space indent, 88-char lines)
- Fixed macro alignment, pointer alignment, brace placement
- Updated .clang-format to use Cpp language (valid enum value)
- Removed clang-tidy pre-commit hook (requires additional setup)
- Pre-commit now runs clang-format for automated formatting
- Verified: All boards still build without errors or warnings
