**Stabilize `RollingAppenderDirectCronTest` by waiting for rolled file
content and relaxing rollover timeout**
Addresses #3046.
> [!IMPORTANT]
> Base your changes on `2.x` branch if you are targeting Log4j 2; use `main`
otherwise.
This PR hardens `RollingAppenderDirectCronTest` against timing races
observed with cron-based rollovers. In practice, `rolloverComplete(...)` can
fire before the first write to the newly rolled file has reached disk, causing
the test to intermittently assert on an empty file. Under scheduler jitter, the
test could also time out while waiting for a rollover.
### What changed (test-only)
- In `rolloverComplete(...)`, wait briefly until the rolled file exists
**and** has non-zero length before asserting its contents:
```java
waitAtMost(2, TimeUnit.SECONDS).until(() -> Files.exists(path) &&
Files.size(path) > 0);
**Why**
- With CronTriggeringPolicy, the rollover completion callback may run before
any event for the new time window is flushed to disk. The test previously
asserted isNotEmpty() immediately and could race with IO, leading to flakiness
(see #3046).
