[I] Dev mode live reload fails with "Already a codec registered with name polaris-events-local" [polaris]

sclee01 opened a new issue, #5844:
URL: https://github.com/apache/polaris/issues/5844

### Describe the bug

In Quarkus dev mode, any code change followed by a request makes the live reload fail,
and the server keeps returning HTTP 500 until it is fully restarted.

### To Reproduce

1. `./gradlew run`
2. Send any request (e.g. get a token) -> OK
3. Add a blank line to any Java file under `runtime/service` and save
4. Send a request again -> live reload is triggered and fails with HTTP 500:

Caused by: java.lang.IllegalStateException: Already a codec registered with name polaris-events-local
at org.apache.polaris.service.events.EventBusConfigurer.configureEventBus(EventBusConfigurer.java:33)

### Expected behavior

Live reload succeeds and the request is served normally.

### Additional context

`EventBusConfigurer` (added in #3973) registers a default codec for `PolarisEvent` on every `StartupEvent`, but never unregisters it. On dev mode restart the Vert.x EventBus is kept, so the second registration fails.

### System information

- OS: Amazon Linux 2023, aarch64
- Java: 21.0.9

I'd be happy to work on a fix.
