[FEATURE] handle redirections for iframed content served by HyperSwitch

[kashif-m]

Feature Description

HyperSwitch's SDK / links is meant to work within top context at the client side. This behaviour changes when we introduce secure links - which are supposed to be iframed within merchant's top context. Any functionality which was consuming top context at the client side needs to be handled accordingly.

Possible Implementation

Major things which needs to be handled

• client side redirections to happen at top context
  • client side redirections happen within current window context - which is assumed to be top (since the SDK integration requires this to be at top level)
  • when using iframed resources, SDK should handle redirection and make sure this happens in the top context
• accessing protocol and hostname
  • this is also fetched from within the current window's context
  • needs to happen at top context
