fix: fully-qualify item types in Api/Data SearchResults docblocks

[Hawksama]

Summary

Every REST list endpoint the module ships (V1/rma, V1/rma/*/comments, V1/rma/*/attachments, V1/rma/*/items, V1/rma/reasons, V1/rma/statuses, V1/rma/resolution-types, V1/rma/item-conditions) currently fails with a 500:

{"message":"Class \"CommentInterface\" does not exist", ...
  #0 …/MethodsMap.php(166): ReflectionClass->__construct('CommentInterface')
  #3 …/DataObjectProcessor->buildOutputDataArray(MageOS\RMA\Model\Comment, 'CommentInterface')
  #4 …/ServiceOutputProcessor->convertValue(
        MageOS\RMA\Model\Data\CommentSearchResults,
        '\\MageOS\\RMA\\Api\\Data\\CommentSearchResultsInterface')
}

Each Api/Data/*SearchResultsInterface.php in the module declares its item type in PHPDoc using the short class name:

namespace MageOS\RMA\Api\Data;

use Magento\Framework\Api\SearchResultsInterface;

interface CommentSearchResultsInterface extends SearchResultsInterface
{
    /**
     * @return CommentInterface[]
     */
    public function getItems(): array;
}

\Magento\Framework\Reflection\TypeProcessor resolves PHPDoc short names against the interface's own use block only — it does not fall back to the file's own namespace — so the string CommentInterface reaches new ReflectionClass() unqualified and throws.

Reproduced against Magento 2.4.8-p5 (PHP 8.3.16) with mage-os/module-rma at dev-main (9a0ae70).

Change

Fully qualify item types in @return and @param on getItems() / setItems() across all 8 Api/Data/*SearchResultsInterface.php files:

-     * @return CommentInterface[]
+     * @return \MageOS\RMA\Api\Data\CommentInterface[]

This matches Magento core convention — e.g. Magento\Customer\Api\Data\CustomerSearchResultsInterface and Magento\Sales\Api\Data\OrderSearchResultInterface both FQ their item types in PHPDoc for the same reason.

Only the interface docblocks are touched; the concrete Model\Data\*SearchResults.php classes already have a matching use for the item interface, so they never hit this path.

Test plan

• V1/rma/1/comments?searchCriteria[pageSize]=1 reproduces the 500 without the patch.
• Same request returns a valid CommentSearchResultsInterface payload after the patch (Magento 2.4.8-p5, PHP 8.3.16).
• CI green.
