Rename Constants to Follow Kotlin Naming Conventions (commons-app#6107)

* Rename Constants to Follow Kotlin Naming Conventions

>This PR refactors constant names in the project to adhere to Kotlin's UPPERCASE_SNAKE_CASE naming convention, improving code readability and maintaining consistency across the codebase.

>Renamed the following constants in LoginActivity:
>saveProgressDialog → SAVE_PROGRESS_DIALOG
>saveErrorMessage → SAVE_ERROR_MESSAGE
>saveUsername → SAVE_USERNAME
>savePassword → SAVE_PASSWORD

>Updated all references to these constants throughout the project.

* Update Project_Default.xml
