📄 Description

Adds support for images and string content in Anthropic tool_result blocks, and explicit errors for unsupported types (search_result, document).

Images use the existing input_text/input_image multimodal tool message pattern from utils/misc.py, which the middleware already handles for downstream providers.

Also extracts a _convert_anthropic_image_source helper to DRY up image conversion, and adds HTTP 400 error handling for conversion failures.

Based on the work in #23004 by @regulad.
