fix: update pre-commit configuration to prevent test_formatting.tf file creation issues

- Add global exclude pattern for temporary test files
- Configure terraform_fmt to not write files during pre-commit (check mode only)
- Add -backend=false to terraform_validate to skip backend initialization
- Remove redundant per-hook excludes (now handled globally)
- Fix CI validation failures caused by malformed temporary test files
