fix(#709): add missing org.springframework.http OSGi import in camel-cxf-all

[jbonofre]

What

Adds the missing org.springframework.http* OSGi package import to the camel-cxf-all bundle.

Fixes #709.

Why

With the CXF version bundled in 4.18, org.apache.cxf.jaxrs.springmvc.SpringWebUtils references org.springframework.http.server.observation.ServerRequestObservationContext (Spring 6 / Micrometer observability). At runtime this failed with:

java.lang.NoClassDefFoundError: org/springframework/http/server/observation/ServerRequestObservationContext
    at org.apache.cxf.jaxrs.springmvc.SpringWebUtils.setHttpRequestURI(SpringWebUtils.java:51)
    ...
Caused by: java.lang.ClassNotFoundException:
    org.springframework.http.server.observation.ServerRequestObservationContext
    cannot be found by camel-cxf-all_4.18.2

camel-cxf-all enumerates specific Spring sub-packages in <camel.osgi.import> (aop, beans, context, core, util, web) but did not import org.springframework.http*. That package is a sibling of org.springframework.web, so org.springframework.web* does not cover it — the package was never wired and the class could not be found.

Note camel-cxf-spring-all is unaffected because it imports the org.springframework* wildcard.

Change

org.springframework.http*;resolution:=optional;version="${camel-osgi-spring-version}",

Marked resolution:=optional and versioned, consistent with the other optional Spring imports in this bundle (these Spring integrations are only used when Spring is on the classpath).

Verification

Built the module and confirmed the generated META-INF/MANIFEST.MF now includes the required package:

org.springframework.http.server.observation;resolution:=optional;version="[6.2,...)"

Scope

Karaf-specific packaging/OSGi-metadata delta only; no Camel-core change.
