Add MainView logging for server loading debug

CHANGELOG.md

@@ -4,3 +4,4 @@
 - Flattened the project structure so sources live at the repository root instead of the nested `iKeyMon/` folder and updated the Xcode project accordingly.
 - Fixed build settings (entitlements, preview assets) and placeholder previews to work with the new layout.
 - Migrated the updated API layer and unified `ServerInfo` model from the previous branch.
+- Added verbose logging in `MainView` to trace server loading, selection, and fetch/ping activity when the list appears empty.
