web-wallet: Update to Node 22 and Resolve Deprecation Warnings

[nortonandreev]

Description:

To accelerate the development of the web-wallet for w3sper, I have updated the engine requirements to Node 22 (which will be the next LTS version) due to web socket compatibility. While there might be a way to use compatible web sockets in Node 20, I didn’t have the time to explore this further due to other priorities. We can revisit this later if needed.

Immediate Actions:

• We need a PR to update the CI configuration to use Node 22. This should be straightforward.

Problem:

• Node 22 introduces a new feature that floods our tests with deprecation warnings (in red), making it difficult to troubleshoot issues. These warnings are caused by deprecated modules, particularly punycode, which is used by many other modules.

Potential Solution:

• Upon investigation, switching to punycode.js seems to eliminate the warnings (see issue).

• I attempted to use the override field in package.json, but I wasn’t successful. I’m unsure whether this is due to an error on my part or if we should address it through some Vite/Rollup config adjustment (e.g., adding a "module alias").

Next Steps:

• Investigate and implement a solution to replace punycode with punycode.js to eliminate the warnings.
• Consider if any Vite/Rollup config tweaks are required to make this change seamless.
