test(core/ethereum): adjust EIP-7702 test vectors

- rename `nonce` to `tuple_nonce` since it's not the same as the tx nonce
- set `to_address` to `m/44'/60'/0'/0/0`-derived address
- test non-empty calldata, empty destination and payment request
- update `chain_id` 0 error message
- add mainnet test vectors

The short version

What changed, and why it matters

This commit only updates test data files for Ethereum EIP-7702 (account abstraction) signing. It renames a test field, adds more test cases, updates expected error messages, and adds mainnet transaction test vectors. There are no changes to the actual firmware or production code, so it does not introduce or fix a security vulnerability in the shipped product.

Recommended action

No security action required; treat as routine test-maintenance commit.

Security signals we found

No strong security signals were identified.

Technical analysis

Evidence from the diff

The diff modifies three JSON fixture files under common/tests/fixtures/ethereum. Changes are purely test-vector maintenance: renaming ‘nonce’ to ‘tuple_nonce’ to avoid ambiguity with transaction nonce, setting to_address to a derivation-path-derived address, adding error cases for payment requests, non-zero value, non-empty calldata, and empty destination, updating expected chain_id 0 error text, and adding a new sign_tx_eip7702_mainnet.json fixture with real mainnet authorize/revoke vectors. No source code, parsing logic, or validation rules are changed.
