Replace 'q' package with Promises

[retyui]

Could you please remove the q library in this React Native pkg. and use JavaScript Promises instead?

Why?

• Smaller app size: q is an unnecessary dependency.
• Cleaner code: Native Promises are standard and easier to read.
• Better performance: Native implementations are often optimized.
