inscription atlas: TEMP debug log to diagnose why prod isn't rendering

Adding console.debug at each rejection point in BlockScene.requestArtifactSlot
and at the entry of OrdpoolInscriptionAtlas.requestSlot. Local code paths
match what the bundled prod build serves; flag wire format includes
ordpool_inscription_image as expected; 6 image inscriptions identified
in the test block, all eligible by vsize and flag — yet the prod page
shows zero spinners and zero images. This logs whether the atlas is
even being asked, and on what data, so DevTools can pinpoint where the
pipeline drops the tx.

Will be reverted once the prod issue is diagnosed.
