fix: Set the Android Application Build Correctly in AS

NOTE: All changes were made in the application codebase

Summary of changes made:

• Deletes the application dependencies that were present in application codebase as they can be dynamically fetched from AS while building app.
• Fixes build-scripts for application(build-nested.sh, gradlew & gradlew.bat) as their incorrect format caused gradle tasks run incorrectly
• Cleans up ignorelist
• Removes duplicate & unused dependencies from gradle file
