feat(find-wallet): Add privacy filter

[Savio-Sou]

Description

Adds an optional "Privacy" wallet property and a filter under the "Smart contract" section for tagging and filtering wallets supporting built-in private transactions.

No wallets are tagged / added in this PR by intention to keep the PR simple to review. To try the filter out, add privacy: true, to a random wallet in wallet-data.ts and build the website locally.

Thanks @Savio-Sou! At a glance this looks good, and I personally love the direction.

@konopkja Mind weighing in here? This PR effectively adds a privacy feature filter. Currently none are marked with it, which was intentional for the PR (but is also likely completely accurate tbh), so checking it would immediately yield "no results".

@Savio-Sou did you have any existing wallets in mind that would fit this? "Wallets that support built-in private transactions" feels a touch vague... I'm not quite sure what this would mean. A "private RPC"? ZK proofs are involved? Curious your thoughts here

Personally love the idea of adding something like this to, at the least, surface it as an important feature... and secondly, to give wallet providers something to strive for since actual respect for privacy in wallet apps is extremely hard to find, and a ❌ Privacy next to their wallet name could help motivate, since human decency doesn't. I'm not sure how I feel though about adding a flag that yields no results though, that's bad UX, so curious the apps @Savio-Sou you may be thinking for this to potentially launch with.

Railway, Payy, Obsidion, and AzGuard are ones that I'm aware of that supports private transactions built-in.

Intentionally left adding them to the wallet list out of this PR to keep things clean. Happy to follow up with separate PRs adding them.

"Wallets that support built-in private transactions" feels a touch vague... I'm not quite sure what this would mean. A "private RPC"? ZK proofs are involved?

Private transactions using ZKPs to conceal senders and/or amounts, yes. I personally won't consider the mere use of private RPC for sending transactions to be private transactions.

Looks great! Thanks again @Savio-Sou...

Per discussion with @konopkja, I've commented out this filter while we're awaiting the listing of at least one privacy-enabled wallet.

@Savio-Sou https://github.com/ethereum/ethereum-org-website/issues/new?template=suggest_wallet.yaml This is the issue template for these—would you have any interest in filling these out for any or all of the wallet suggestions you made?

e.g.

• Railway
• Payy
• Obsidion
• AzGuard

Merging in the meantime! 🎉
