Fill the embedded wallet section

[Hugoo]

As of the current state, the embedded wallet page has no content:

https://wallet.page/embedded/summary

I suggest to remove this from the sidebar until there is real content as for now, it makes things more messy.

More context:

This section is currently unfilled but expect this section to cover embedded wallets in dApps & mobile; web3modal, alchemy accountkit, privy, biconomy, etc

I'll rename the issue title.

Yeah. The embedded wallets are implemented to kind of force the schema to account for more than just 2 wallet types (previous parts of the code assumed that each wallet just had a hardwareWallet boolean bit, rather than a enum-like "wallet type"). Now the schema has caught up to accommodate this more properly, but we haven't focused on actually filling in any embedded wallet data.
