chore: remove old token details page

[bergeron]

Description

There used to be an inner token details page nested within the asset page, that you accessed from the kebab menu:

But with the redesign of the asset page in #24522, there is no longer any way to access this page. The equivalent data and hide functionality is now directly on the main asset page.

This PR removes the component.

I considered trying to maintain this route and point it to the main asset page. But I think its unlikely anyone is keeping bookmarks to it.
