📝 Detailed Description

What does this PR do?

This PR adds per-entrypoint authorization snapshot tests for the markets contract in contracts/markets/tests/auth_snap.rs. The new tests verify that each state-changing entrypoint requires the expected authorization and provide regression coverage for future changes.

Why is this change needed?

Authorization requirements are a critical security guarantee for the markets contract. These snapshot tests make the expected authorization behavior explicit and help prevent accidental regressions by failing whenever authorization requirements change unexpectedly.

How was this tested?

• Added authorization snapshot tests for the markets contract.
• Executed the relevant test suite with cargo test.
• Verified that the generated snapshots match the expected authorization behavior.

Alternative Solutions Considered

Individual authorization assertions for each entrypoint were considered, but snapshot tests provide clearer regression detection while requiring less maintenance as authorization behavior evolves.
