Smart Contract Tests: Add coverage for Rate limiting module boundaries

[p3ris0n]

Category: Blockchain / Smart Contract Development

Objective: Write comprehensive Rust unit tests for Rate limiting module boundaries.

Detailed Description: Increase test coverage in contracts/token/src/test.rs specifically focusing on Rate limiting module boundaries. Ensure we test happy paths, edge cases, and expected failures (#[should_panic]).

Acceptance Criteria:

• Test must pass locally via cargo test.
• Verify test actually fails when contract logic is intentionally broken (mutation testing).

Technical Requirements: Rust, Soroban SDK

Deliverables:

• New test functions in the test modules

Testing Requirements:

• Run cargo test --package bc-forge-token to verify.

Estimated Difficulty: Intermediate

Points: 200
