Transak now requires widget URLs to be generated server-side via their
gateway session API. Direct query-parameter URLs are deprecated.
- Add getAccessToken() with 7-day caching for partner access tokens
- Add createSecureWidgetUrl() that calls the gateway session endpoint
- Falls back to legacy direct URL if gateway returns an error (e.g.
production IP not yet whitelisted)
- Update rCart and rFlows to use the secure API
