refactor: improve diff handling for EOL changes and enhance text diff… (#1177)

* 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.

* localization: update translations to include EOF handling in ignore whitespace messages

- Modified the ignore whitespace text in multiple language files to specify that EOF changes are also ignored.
- Ensured consistency across all localization files for the patch application feature.

* revert: Typo in DiffResult comment

* revert: update diff arguments to ignore CR at EOL in whitespace handling (like before changes)

* revert: update translations to remove EOF references in Text.Apply.IgnoreWS and fixed typo in Text.Diff.IgnoreWhitespace (EOF => EOL)
