fix(image-pipeline): surface per-image failures in the event log

Two gaps made posts 650/657 appear to silently "lose" their featured
images on 2026-04-20:

1. The batch provider tagged each failed key with ['error' => ...] but
   the ERROR log line it emitted didn't identify which key failed, so
   operators couldn't tell image_a from image_b in the event log when
   one of two parallel requests died.

2. Image_Pipeline::process_image_a/_b folded the per-key error into
   $result['errors'] and returned silently, with no WARNING row. Ops
   only learned about the miss when the outer catch in the caller fired
   — and on the 2026-04-20 incident that outer catch didn't fire, so
   nothing was logged at all except an unrelated pricing warning.

Fix:

- class-open-router-image-batch.php: collect_result() takes the request
  key as its first argument and every Logger::error message reads
  'OpenRouter batch image gen <class> for key "<key>": <detail>'.
  Matches the shape of OpenRouter_Image_Support::log_retry.

- class-image-pipeline.php: process_image_a and process_image_b now
  emit a Logger::warning('image_pipeline') row whenever $image_data is
  missing or carries an error key, in addition to pushing to
  $result['errors']. The warning fires whether or not the outer catch
  runs.

Test: ImagePipelineTest::test_partial_batch_failure_emits_warning_log_row
mocks $wpdb, runs the pipeline with image_a erroring, and asserts at
least one warning/image_pipeline row was inserted.

No behavior change beyond logging; cost impact zero.

Part of the v0.8.0 image bundle (issues from thread image-mime-bug).
