CAMEL-24264: camel-aws2-translate - throw when pojoRequest=true and the body is the wrong type

[oscerd]

Child of CAMEL-24261 (completing CAMEL-23462 across the AWS2 producers).

Problem

With pojoRequest=true, Translate2Producer.translateText only acted when the
body was a TranslateTextRequest; any other body fell through the instanceof
with no else, so no AWS call was made, no response was set, and the original
body was returned with no error.

Fix

} else {
    throw new IllegalArgumentException(
            "translateText operation requires TranslateTextRequest in POJO mode");
}

Test

translateTextWithPojoRequestAndWrongBodyTypeThrows sends a wrong-typed body to
the existing pojoRequest=true route and asserts the message. Verified to fail
(silent no-op) before the fix. Class 4/4 green.

Docs / backport

The shared 4.22 upgrade-guide entry was added with CAMEL-24263. Main only, matching
the CAMEL-23462 precedent (behaviour change, shipped in a minor, not backported).

[gnodet]

Clean, minimal fix that follows the established CAMEL-23462 pattern for rejecting wrong-type bodies in POJO mode. The fix, test, and dependency addition are all correct.

Verified details:

• The fix correctly adds an else clause throwing IllegalArgumentException when pojoRequest=true but the body is not a TranslateTextRequest — structurally identical to the pattern established in CAMEL-23462 for BedrockProducer.
• The test correctly uses hasRootCauseInstanceOf(IllegalArgumentException.class) to unwrap through the CamelExecutionException wrapper, and reuses the existing direct:translatePojoText route.
• The assertj-core test dependency is justified and correctly omits the version (managed by parent BOM).
• No mixing of AssertJ and JUnit assertions within the same test method.
• Git history confirms the silent fall-through was original code with no prior intentional changes.
