fix(adsense): Disable output buffer causing content loss

The output buffer in adsense-delay.php was causing conflicts with
zlib compression buffer, resulting in ads being generated but not
appearing in final HTML.

Root cause: Multiple output buffers (zlib + adsense-delay) were
nested improperly, causing ob_end_flush() failures and content loss.

Solution: Disable the output buffer since AdsensePlacementRenderer
already generates scripts with type="text/plain" data-adsense-push.
The buffer was redundant and only needed for external AdSense sources.

Debug logs confirmed:
- Filter generates ads correctly (598+601 chars)
- Content exists after filter (54765 chars)
- But ads missing in final HTML (0 roi-ad-slot found)
- ob_end_flush() errors in debug.log
