Regression: core.forms.components.version > 1.1.66 causes Forms API/classpath failures

### Expected Behaviour
Upgrading AEM Forms Core Components should not break consumer build/tests.
The project should build successfully without adding local compatibility stubs/shims for missing Adobe Forms classes.

### Actual Behaviour
When `core.forms.components.version` is upgraded above `1.1.66`, build/test failures occur in `core`, including:
- compile-time API mismatch (missing override for `getOptionScreenReaderLabels()`),
- runtime/test classloading failure (`NoClassDefFoundError: com/adobe/fd/fp/api/exception/FormsPortalException`),
- binary compatibility error observed in tests (`IncompatibleClassChangeError` on USC `Query` type shape mismatch).

### Reproduce Scenario (including but not limited to)
Regression appears when moving from known good Forms components version to newer versions.

#### Steps to Reproduce
1. In `pom.xml`, set:
- `core.forms.components.version` to a version `> 1.1.66`
2. Run:
```zsh
mvn clean install

#### Platform and Version
IntelliJ IDEA 2026.1.3

#### AEM Version (mention the exact version in case of cloud SDK)
io.wcm.maven:io.wcm.maven.aem-dependencies:6.6.3.0000

#### AEM Forms Version
Last known working: core.forms.components.version=1.1.66
Failing versions: > 1.1.66

#### Sample Code that illustrates the problem
Affected consumer classes:
components/checkboxgroup/CheckBoxGroupImpl.java
components/radiobutton/RadioButtonImpl.java

Method required by newer API contract:
@Override
public String[] getOptionScreenReaderLabels() {
return .getOptionScreenReaderLabels();
}

#### Logs taken while reproducing problem
[ERROR] ...CheckBoxGroupImpl is not abstract and does not override abstract method getOptionScreenReaderLabels() in com.adobe.cq.forms.core.components.models.form.OptionsConstraint
[ERROR] ...RadioButtonImpl is not abstract and does not override abstract method getOptionScreenReaderLabels() in com.adobe.cq.forms.core.components.models.form.OptionsConstraint

NoClassDefFoundError: com/adobe/fd/fp/api/exception/FormsPortalException

java.lang.IncompatibleClassChangeError: class com.adobe.cq.forms.core.components.internal.models.v1.formsportal.DraftsAndSubmissionsImpl$QueryImpl can not implement com.adobe.forms.foundation.usc.model.Query, because it is not an interface

Start with pom.xml and reproduce the failure using core.forms.components.version above 1.1.66 with mvn clean install. Then inspect components/checkboxgroup/CheckBoxGroupImpl.java and components/radiobutton/RadioButtonImpl.java alongside the reported Forms API and classloading errors. Done means the project builds and tests without compatibility stubs or shims across the affected versions.
