refactor(pytest): integrate EIP report generation into spec_version_checker plugin

Move EIP version report generation from external script into the
spec_version_checker pytest plugin to eliminate brittle regex parsing
of console output and improve maintainability.

- Add EIPVersionFailure dataclass to capture failure data directly
- Implement generate_eip_report_markdown() function within plugin
- Use pytest_sessionfinish hook to generate reports automatically

 - 🐞 zkEVM marked tests have been removed from `tests-deployed` tox environment into its own separate workflow `tests-deployed-zkevm` and are filled by `evmone-t8n` ([#1617](https://github.com/ethereum/execution-spec-tests/pull/1617)).
 - ✨ Field `postStateHash` is now added to all `blockchain_test` and `blockchain_test_engine` tests that use `exclude_full_post_state_in_output` in place of `postState`. Fixes `evmone-blockchaintest` test consumption and indirectly fixes coverage runs for these tests ([#1667](https://github.com/ethereum/execution-spec-tests/pull/1667)).
