Fix page navigation in iframe

[MAX-786]

fixes #124

after looking into this it seems that if we prefix iframe url like i typedin https://localhost:5173/#! and then when you navigate to another page in adminUI, then adminUI changes it to https://localhost:5173/new-path?token=xyz#! and so it works locally but it will not work current netlify so, even if i let adminUI do this https://localhost:5173/#!/new-path this just opens up the root route of the site as you can see here this will open up homepage instead of test page : https://hydra-vue-f7.netlify.app/#!/test

So current navigation in iframe works like this: after navigating to another page in iframe,

• hydrajs detects any changes in href of the window i.e. it checks if pathname is changed or not and also if hash is changed or not.
• then sends the new path to adminUI and adminUI routes to this path (but doesn't change the iframe src which saves us from the extra reloads.
