🚀 Major rewrite with full PayPal Orders API v2 support

This release introduces a complete overhaul of the payment flow, API models, and service structure. ⚠️ Breaking changes included.

✨ New Features #

• Added PayPal Orders API V2 support (create order + capture).

• Strongly-typed request/response models:

  • PayPalOrderRequestV2
  • PaypalPaymentModelV2
  • PayPalCaptureOrderResponse

• Added full enums for:

  • shipping_preference
  • payment_method_preference
  • landing_page
  • user_action
  • item.category

• Added safer custom URL scheme defaults (paypal-sdk://success, paypal-sdk://cancel) for return/cancel handling.

• Support both secure and insecure flows:

  • Secure (recommended): Backend creates order & handles capture.
  • Client-side (testing only): App creates order and captures it.

• Improved WebView behavior & progress UI.

🔒 Security Improvements #

• Added strict protection against exposing PayPal clientId and secretKey in production.
• New flag: overrideInsecureClientCredentials to bypass security (sandbox/testing only).
• Added checks preventing live-mode token generation without backend.

🔧 Enhancements #

• More reliable approval link extraction (approve and payer-action).
• Better error models and error surface handling.
• Cleaner separation between backend-driven and client-driven flows.
• More descriptive callback models for success, error, and cancel events.

⚠️ Breaking Changes #

• Old V1 models and flows removed or renamed.
• PaypalPaymentModel replaced with PaypalPaymentModelV2.
• executePayment replaced with order capture.
• Removed reliance on PayerID (not used in PayPal V2).
• Package API simplified and reorganized.

This package simplifies integrating PayPal payments into your mobile app. Key features include:

• Seamless in-app PayPal WebView checkout
• User-friendly payment flow
• Secure transaction handling
• Customizable UI components
• Real-time payment status updates

Future enhancements include more payment options, fraud protection, subscription support, and analytics improvements.
