Refactor variable names to adhere to naming conventions (#6111)

* 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

* Refactor variable names to adhere to naming conventions

Renamed variables to use camel case:
-UPLOAD_COUNT_THRESHOLD → uploadCountThreshold
-REVERT_PERCENTAGE_FOR_MESSAGE → revertPercentageForMessage
-REVERT_SHARED_PREFERENCE → revertSharedPreference
-UPLOAD_SHARED_PREFERENCE → uploadSharedPreference

Renamed variables with uppercase initials to lowercase for alignment with Kotlin conventions:
-Latitude → latitude
-Longitude → longitude
-Accuracy → accuracy

Refactored the following variable names:
-NUMBER_OF_QUESTIONS → numberOfQuestions
-MULTIPLIER_TO_GET_PERCENTAGE → multiplierToGetPercentage
