fix(responses): preserve cache_control in Responses API -> Chat Completion transformation (#27727)
* fix(responses): preserve cache_control in Responses API -> Chat Completion transformation

cache_control injected by AnthropicCacheControlHook was silently dropped when
_transform_responses_api_content_to_chat_completion_content rebuilt content blocks
with only {type, text}. Now copies cache_control through so Anthropic prompt caching
works correctly when using client.responses.create with cache_control_injection_points.

* fix(responses): preserve cache_control for input_image and input_file blocks

Extends the cache_control fix to image and file content blocks, which were
also silently dropping cache_control during the Responses API -> Chat Completion
transformation. Adds tests for all three content block types.
