* fix(azure): strip output-only reasoning content from Responses input
* test(azure): cover idless encrypted reasoning replay
* fix(azure): preserve existing status handling during reasoning replay
* fix(azure): scope reasoning content filtering by provider
* fix(azure): drop status and content from replayed reasoning items
* fix(azure): forward non-object input items and drop reasoning content on every Azure route
* fix(azure): drop replayed reasoning content only under drop_params
Reasoning status is still dropped on every Azure route. Caller-set reasoning
content now follows the created_by convention from #48783: it is dropped when
drop_params is on and forwarded otherwise, so Azure answers its own 400.
