fix: Use GitHub secret names directly without GHUI_ prefix

- Changed build.gradle to use KEYSTORE_PASSWORD, KEY_PASSWORD, KEY_ALIAS directly
- Updated workflow to pass secrets without renaming to GHUI_ prefix
- This matches the actual secret names configured in GitHub
- Also fixed null handling for KEY_ALIAS using safe navigation operator
