PR Summary

Low Risk
Low risk: updates test fixtures and expands regression coverage without changing verifier logic or production code paths.

Overview
Adds a new regression fixture set for Starknet 0.14.3 (including example_proof_facts.json) and extends the regression_verify_proof_from_old_prover rstest to run against it.

Updates the shared apollo_transaction_converter example_proof_facts.json to use PROOF_VERSION_V1 (0x50524f4f4631) instead of the previous version value.
