Add Sparrow and Phoenix wallets

[Copinmalin]

Summary

This PR adds two privacy-focused Bitcoin wallets to the Crypto Wallets category:

• Sparrow Wallet
• Phoenix Wallet

Rationale

Sparrow Wallet is a desktop Bitcoin wallet focused on security, privacy, and self-custody workflows.

Phoenix Wallet is a self-custodial mobile Bitcoin wallet focused on Lightning payments.

Together, they improve Bitcoin wallet coverage in the Crypto Wallets category by adding one desktop wallet for advanced self-custody and one mobile wallet for everyday Lightning payments.

Changes

• Added Phoenix Wallet to Crypto Wallets private alternatives
• Added Sparrow Wallet to Crypto Wallets private alternatives
• Added matching JPG logos under public/app-logos/

ACK
It is important to propose sovereign and censorship-proof solutions when discussing currency.

Besides the formatting suggestion above, I support this PR. Sparrow offers precise coin control, essential for privacy. Phoenix is great for Lightning, which suits everyday transactions with good privacy.

As a side-note (not directly related to this PR), it is surprising that the Payments section has Apple Pay as a privacy-friendly option but not Bitcoin.

Hi maintainers, gentle ping on this PR.

The previous formatting feedback has been addressed and the review thread is now resolved. As far as I can see, the PR is mergeable and the CLA check is signed.

Could you please review and merge it when you have a moment? If there is anything still blocking the merge, or if the inclusion of Sparrow Wallet / Phoenix Wallet needs more rationale, I’d be happy to clarify or adjust the PR.

Thanks!
