fix: Add comprehensive port cleanup to prevent test failures

## Changes:
- Added port 8080 cleanup before starting test suite in rit-direct.sh
- Added port cleanup after each individual test to prevent conflicts
- Tests were failing due to hanging Spring Boot processes on port 8080

## Root Cause Identified:
- All test failures were due to port conflicts, not application issues
- Spring Boot apps sometimes don't cleanup properly, leaving hanging processes
- Sequential execution without cleanup caused cascading failures

## Impact:
- Should achieve 100% pass rate by eliminating port conflict root cause
- Enables reliable test suite execution without manual intervention
