fix: Address code review findings from commit 7caee47

## Dead Code Removal
- Removed unused LOGGER field and getLogger() method from PropertyUtil
- Removed unused imports: java.util.logging.Level and java.util.logging.Logger
- Removed testPrivateGetLogger() test that verified dead code

## Documentation Consistency
- Added @SInCE 1.0 tags to all FileException non-deprecated constructors
- Matches CommonsIOException pattern for API version tracking
- Addresses issue #142 (missing @SInCE tags)

## Log-and-Throw Anti-Pattern Fix
- Removed redundant logging in SoapUtil.getSoapFactory()
- Follows same "log or throw, not both" principle as commit 7caee47
- Maintains consistency with PropertyUtil refactoring

## Test Results
- All 286 tests pass (was 287, removed 1 dead code test)
- No compilation errors
- Consistent exception handling patterns across codebase
