feat(nameguard): Add ENSNode API for primary name resolution

Tests fail because output from ENSNode API is different than from RPC.

E.g. for address 0xFD9eE68000Dc92aa6c67F8f6EB5d9d1a24086fAd we got exampleprimary.cb.id from ENSNode but null from Alchemy.

The decision is that ENSNode API behaviour is the correct one (if the primary name is unnormalized then we say there is no primary name) so we need to fix tests. Probably unnormalized state in the endpoint is no longer valid.
