Show foreign Assets and Foreign Asset Balances in Assets Tab

[alistair-singh]

Asset Hub Polkadot now supports bridged assets in a new instance of the assets pallet called foreignAssets. The current Assets tab in the polkdate-js UI does not show these assets or the asset balances. This is confusing for users who are using polkadot-js-app to search for their funds. This data is available to users if they query it manually using chain state, but is not available in the Assets tab which is the most obvious place that users look.

A user should be able to browse foreign assets and see foreign assets balances for accounts in their wallet in the Assets Tab in the polkadot-js-app.
See this example of subscan: https://assethub-polkadot.subscan.io/assets?tab=foreign-assets

The main motivation is that users are looking for assets, going to the Assets Tab in the app, not seeing foreign assets, and thinking that transfers are not yet complete or have failed. (Dont see their assets and panic)

Our environment/dapp is the Snowbridge Ethereum-Polkadot bridge. And users are trying to find their assets after a transfer.

Snowbridge has a bridge transfer utilility app that has its own tracking where we link to Subscan to show transfer success; we also show foreign assets balances. Subcan provides this data as well in their block explorer. We have also done work with various wallets to display foreign assets at a wallet level. However some users go to polkadot-js app.
