[PR] CAMEL-24305: Fix autowiring of KafkaClientFactory via addComponent() [camel]
gnodet opened a new pull request, #25230:
URL: https://github.com/apache/camel/pull/25230
## Summary
_Claude Code on behalf of gnodet_
Fixes [CAMEL-24305](https://issues.apache.org/jira/browse/CAMEL-24305): `KafkaComponent` does not autowire a custom `KafkaClientFactory` bean when the component is registered via `addComponent()` (the path used by Spring Boot).
### Root Cause
When a component is registered via `CamelContext.addComponent()`, the lifecycle order is:
1. `ServiceHelper.initService(component)` — calls `doBuild()` + `doInit()`
2. `postInitComponent()` — triggers autowiring via `LifecycleStrategySupport.doAutoWire()`
Since `KafkaComponent.doInit()` was creating a `DefaultKafkaClientFactory` in step 1, the field was already non-null when autowiring checked it in step 2, and the custom factory was silently skipped.
This is a regression from [CAMEL-17262](https://issues.apache.org/jira/browse/CAMEL-17262) (commit `74c5a4ad2a7`), which reintroduced the bug originally fixed in [CAMEL-16500](https://issues.apache.org/jira/browse/CAMEL-16500) (commit `5ae05407c02`).
### Fix
- **KafkaComponent**: Move default `KafkaClientFactory` creation from `doInit()` to `doStart()`, giving the autowiring lifecycle strategy time to inject a custom factory before the default is created. This follows the same pattern used by `MapstructComponent` and `VertxHttpComponent`.
- **KafkaEndpoint**: Restore the `DefaultKafkaClientFactory` fallback in `doBuild()` (originally from CAMEL-16500) for resilience when the endpoint builds before the component starts.
### Tests
- Added `testKafkaComponentAutowiringViaAddComponent()` — exercises the `addComponent()` path with a custom `KafkaClientFactory` registered in the registry, verifying autowiring works
- Added `testKafkaComponentDefaultFactoryWhenNoneRegistered()` — verifies the default factory is still created when no custom factory is available
- Existing `testKafkaComponentAutowiring()` continues to pass (exercises the `getComponent()` path)
- All 196 unit tests in `camel-kafka` pass with 0 failures
