fix: deflake nomination test by using injected clock

## Description

The nomination test was flaky because `Nominate()` and `Nominated()`
used `time.Now()` directly while the test used `time.Sleep()` for
real-time delays. In CI environments with timing jitter, the 21-second
sleep could sometimes not exceed the 20-second nomination window.

This fix injects the clock into StateNode so nomination timing uses
the test's fake clock instead of real time.

## Testing

```
go test ./pkg/controllers/state/... -v
go test ./pkg/controllers/... -count=1
```

All tests pass. The nomination test now runs instantly instead of
sleeping for 21 seconds.
