contracts: add v3 Stage7702Module (EIP-7702) Go bindings

Vendor the compiled Stage7702Module artifact from wallet-contracts-v3
(built from source at 7a864d6, solc 0.8.28 / viaIR / paris, matching the
canonical settings of the sibling v3 artifacts) and wire its abigen Go
bindings, following the Stage1Module/Stage2Module pattern.
