[ZK-MONEY]: Empty opportunities for ERC4626 assets

[LHerskind]

As ZK Money is not showing "exit" in the same way it is showing "enter", it is a little weird for exiting the fungible positions because I can click earn for the assets, but that would just get me into an empty opportunities page because as we don't have cards setup for this.

Going back to the age-old discussion around fungible positions, I think that it would make sense for us if we have cards for everything that is fungible, as entering and exiting for these would then be the same user flow. When clicking the claim & exit, we will anyway be showing the user a page like the one we have for deposits. Doing so would let us differ between tokens and earn positions where earn would be the non-fungible and async ones (DCA, Element, Virtual assets).
