feat: add workspace-specific default clone directory functionality (#1183)

* 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)

* feat: add workspace-specific default clone directory functionality

- Implemented logic in Clone.cs to set ParentFolder based on the active workspace's DefaultCloneDir if available, falling back to the global GitDefaultCloneDir.
- Added DefaultCloneDir property to Workspace.cs to store the default clone directory for each workspace.
- Updated ConfigureWorkspace.axaml to include a TextBox and Button for setting the DefaultCloneDir in the UI.
- Implemented folder selection functionality in ConfigureWorkspace.axaml.cs to allow users to choose a directory for cloning.
- This closes issue #1145
