chore_: add a status proxy to the nodefleet rpc as a primary service provider

[friofry]

here is the new RPC providers call:

• status-proxy (proxy nodefleet)
• status-proxy-fallback (proxy infura)
• status-proxy-fallback2 (proxy grove)
• main (nodefleet)
• fallback (infura)

I've tested it on the desktop using the test credentials, the rpc client works fine without falling back to other providers (unless I set the wrong credentials)

Closes #5901

As discussed on Discord, we will not be adding nodefleet (alphafleet.io) as a direct provider for now, as to not expose tokens
