What is changed and how does it work?

controller: Fix limiter not functioning well in high concurrency scenarios
- In high concurrency scenarios, time may appear rollback because the `now` value passed from outside. high mutext completion leading to more non-sequential execution orders.
- Time rollback allows advancing more tokens, which can cause the issue. even result in no limit for the controller.
- Fix the problem by avoiding time rollback; instead of acquiring time again within the lock to fix it, as this might incur high costs when frequently acquiring time.
