issue: #42457
Replace unsafe ExpectedCalls modification with atomic.Int32 state
tracking to avoid race conditions in concurrent test execution. Changes
include:
- Use atomic counters instead of direct mock ExpectedCalls manipulation
- Add RunAndReturn with atomic state transitions for thread safety
- Remove github.com/samber/lo dependency
This prevents data race when mock framework and test goroutines access
ExpectedCalls concurrently.
