Subject: [PATCH] fix: use thinking.adaptive for Opus 4.7 in ReasoningEffort
 and Reasoning paths

Opus 4.7 rejects thinking.type="enabled". The effort-suffix and
-thinking suffix paths already handled this, but the ReasoningEffort
and Reasoning parameter paths still sent "enabled". Now all paths
use "adaptive" + output_config.effort for Opus 4.7.
