Migrate all integration tests to use NIO2 Path-based methods

This commit migrates all Maven integration tests from File-based operations
to the new NIO2 Path-based methods introduced in the previous commit.

Changes made:
- Replaced extractResources() with extractResourcesAsPath() in 704 test files
- Updated File variable declarations to Path where appropriate
- Replaced new File(dir, subpath) with dir.resolve(subpath) patterns
- Updated .getAbsolutePath() calls to .toString() for Path variables
- Fixed extractResources().toPath() patterns to use extractResourcesAsPath()

Migration statistics:
- 704 integration test files successfully migrated
- All tests compile successfully with new Path-based API
- Maintains full backward compatibility for any remaining File usage

The migration was performed using an automated script (migrate-its-to-nio2.py)
that identified and transformed common File-to-Path patterns while preserving
the original test logic and functionality.

Benefits:
- Modern NIO2 API usage throughout integration test suite
- Better performance with Path operations
- Improved cross-platform file handling
- Consistent API usage across all integration tests
