Implement Bridge to Aurora button

[jamesmudgett]

From supported assets detail screen (on Aurora... NEAR) we will want to add a quick link to bridge. See supported assets (note all in the image below should include the bridge button)

Example button placement

Example modal for first click... subsequent clicks on bridge will not show the modal.

(clicking Open... should launch a new tab to rainbowbridge.app)

@rmcfadden3 please review and provide new copy for the modal.
