Add end-to-end tests for submission rate limiting

Implement comprehensive end-to-end tests for all 17 submission types to verify the rate limiting fix. This includes testing the 5/minute limit, the 20/hour limit, and the 60-second cooldown period across park creation/updates, ride creation, and company-related submissions (manufacturer, designer, operator, property owner). The tests are designed to systematically trigger rate limit errors and confirm that submissions are correctly blocked after exceeding the allowed limits.
