refactor: improve diff handling for EOL changes and enhance text diff display

- Updated `Diff.cs` to streamline whitespace handling in diff arguments.
- Enhanced `DiffContext.cs` to check for EOL changes when old and new hashes differ, creating a text diff if necessary.
- Added support for showing end-of-line symbols in `TextDiffView.axaml.cs` options.
