CHNL-17243: Handle lifecycle events from JS

[belleklaviyo]

Description

Calls presentIAF() when receiving formWillAppear and created new method dismissIAF() for receiving theformDisappeared case.

Check List

• Are you changing anything with the public API?
• Have you tested this change on real device?
• Are your changes backwards compatible with previous SDK Versions?
• Have you added unit test coverage for your changes?
• Have you verified that your changes are compatible with all the operating system version this SDK currently supports?

Manual Test Plan

In this mini demo I added some print statements to see when the different messages were being received. You can also tell the webview is dismissed when the form is dismissed as the rest of the app is interactable again/you can navigate away -- as well as reopen the form, etc.

I'm seeing the PR for this is merged. Are you able to get the events over the JS bridge?

nvm I'm seeing the demo now and it does look like you are indeed receiving those! Nice

Nice.

At this moment, while testing, the SDK is still receiving the outdated formAppeared and not the updated formWillAppear -- so it does not actually successfully decode into the event (unless you change back all instances to formAppeared) but going ahead and keeping this in as I imagine the naming on the sending side will be updated soon

@timstephens-k is there a branch with the changed event names that Belle can use to test locally? Is it this?

[belleklaviyo]

found this branch to test on and confirmed it is working with formWillAppear -- also tested with two live forms and only one appeared in app, so double display seems to already be prevented by the time the SDK receives the events EDIT: nvm it is still receiving two popups simultaneously but won't add anything to guard this as this will be handled on the fender side if at all
