Add skeleton for porfolio value sum

[fricoben]

Here we have the sum of my portfolio value that takes more time to charge than the rest which gives me a strange buggy impression, to get rid of this buggy impression I propose you add a skeleton to this section (including the privacy Icon).

You can use loading.tsx to create this skeleton, please be sure to pull origin because of this change https://github.com/lfglabs-dev/starknet.quest/pull/935
