Upgrade the mainnet offline-signing material from specVersion 7002000 (txVersion 7) to specVersion 8000000 (txVersion 8) in preparation for the Polymesh mainnet v8 runtime upgrade scheduled before July 22 2026. The v8 metadata is derived from the live testnet v8 metadata (which has already upgraded) with two surgical patches to match mainnet chain config: the specName string is replaced from polymesh_testnet to polymesh_mainnet, and the SS58Prefix constant value is replaced from 42 to 12. These are the only chain-specific differences between the two networks' v8 metadata; all pallet/call indices are identical since both run the same v8 runtime binary. Also adds mainnetRawTx test fixtures (signed and unsigned transfer and CDD-registration transactions built against the v8 mainnet metadata), and fixes a pre-existing bug in mainnet builder tests where specVersion and txVersion assertions incorrectly compared against testnetMaterial instead of mainnetMaterial.

The Polymesh mainnet runtime upgrade to v8 is scheduled before July 22 2026 (CECHO-1476). This PR prepares the BitGoJS offline-signing material ahead of the cutover so that:
mainnetMaterialexported from@bitgo/sdk-coin-polyxcorrectly describes the v8 pallet/call structure, enabling wallets and the HSM to build and parse v8 transactions immediately after mainnet upgrades.BITGOJS_TEST_PASSWORDintegration test) is unchanged.The v8 metadata is identical in call-index structure to the testnet v8 metadata (same runtime binary), with two chain-specific byte patches: the
polymesh_testnetspecName string is replaced withpolymesh_mainnet, and theSS58Prefixconstant value is changed from 42 to 12. These are the only differences between the two v8 deployments; all pallet indices are shared.Test plan
