[Bug] MultiTopicsConsumer still received message with older ConsumerEpoch after redeliverUnacknowledgeMessages()

### Search before reporting

- [x] I searched in the [issues](https://github.com/apache/pulsar/issues) and found nothing similar.

### Read release policy

- [x] I understand that [unsupported versions](https://pulsar.apache.org/contribute/release-policy/#supported-versions) don't get bug fixes. I will attempt to reproduce the issue on a supported version of Pulsar client and Pulsar broker.

### User environment

- broker version: 4.0.8
- client version: 4.1.1 (java)

### Issue Description

# configs
- producer config
- enableBatching(true)
- blockIfQueueFull(true)
- .batchingMaxMessages(100)
- consumer config
- subscriptionType(SubscriptionType.Exclusive)
- subscriptionInitialPosition(SubscriptionInitialPosition.Earliest)
- enableBatchIndexAcknowledgment(false)

# What I did
- produce messages with property "sequence", then consume them and validate sequence number.
- cumulative acknowledge every `groupSize` message received
- `redeliverUnacknowledgedMessages` in schedule, and reset sequence number.

# Expected
assume current epoch = 0
if `lastAckNumber = 1000`，and number of current received message is `1300` which matches `expectedSequenceNumber`, after calling `redeliverUnacknowledgedMessages()`, it should received a message with number `1001` with higher `comsumerEpoch` and `redeliveryCount`

# Got
A random message with number > `1001`, `consumerEpoch = 0`, `redeliveryCount = 0`
And other message with bigger batch index in the same batch(entry) filltered out.
see logs below.

### Reproducing the issue

```java
@SneakyThrows
private void produceMessages(Producer producer, int count) {
for (int i = 0; i < count; i++) {
producer.newMessage().property("sequence", String.valueOf(i))
.value(("message-" + i).getBytes())
.send();
}
}

@SneakyThrows
private void consumeAndRedeliverRoundtrip(Consumer consumer, int groupSize, long interval) {
long expectedSequenceNumber = 0;
long lastAckNumer = 0;
int count = 0;
long last = System.currentTimeMillis();
while (true) {
var msg = consumer.receive(10, TimeUnit.SECONDS);
if (msg == null) {
log.info("No more messages to consume.");
return;
}

// Validate sequence - should be strictly increasing, gap indicates message loss
String sequenceStr = msg.getProperty("sequence");
if (sequenceStr != null) {
long actualSequence = Long.parseLong(sequenceStr);
if (actualSequence != expectedSequenceNumber) {
log.error("Sequence gap detected! Expected: {}, Actual: {}", expectedSequenceNumber, actualSequence);
throw new RuntimeException("Sequence gap detected! Expected: " + expectedSequenceNumber
+ ", Actual: " + actualSequence);
}
}
count ++;
if (count == groupSize) {
consumer.acknowledgeCumulative(msg);
count = 0;
lastAckNumer = expectedSequenceNumber;
}
expectedSequenceNumber++;

long cur = System.currentTimeMillis();
if ( cur - last >= interval ) {
consumer.redeliverUnacknowledgedMessages();
expectedSequenceNumber = lastAckNumber + 1; // reset expected seq
last = cur;
Thread.sleep(100);
}
}
}
```

Start with the Java ConsumerBase handling shown by the old-epoch filter logs and trace redeliverUnacknowledgedMessages() through the consumer path. Reproduce the issue with the provided produceMessages and consumeAndRedeliverRoundtrip snippets, then verify that redelivered messages begin at the last cumulative acknowledgment with a higher consumer epoch and redelivery count.
