Fixes#19478
The stream_chunk_builder function was not handling image chunks from
models like gemini-2.5-flash-image. When streaming responses were
reconstructed (e.g., for caching), images in delta.images were lost.
This adds handling for image_chunks similar to how audio, annotations,
and other delta fields are handled.

* fix(vertex_ai): convert image URLs to base64 in tool messages for Anthropic
Fixes#19891
Vertex AI Anthropic models don't support URL sources for images. LiteLLM
already converted image URLs to base64 for user messages, but not for tool
messages (role='tool'). This caused errors when using ToolOutputImage with
image_url in tool outputs.
Changes:
- Add force_base64 parameter to convert_to_anthropic_tool_result()
- Pass force_base64 to create_anthropic_image_param() for tool message images
- Calculate force_base64 in anthropic_messages_pt() based on llm_provider
- Add unit tests for tool message image handling
* chore: remove extra comment from test file header
* fix(vertex_ai): replace custom model names with actual Vertex AI model names in passthrough URLs (#19948)
When the passthrough URL already contains project and location, the code
was skipping the deployment lookup and forwarding the URL as-is to Vertex AI.
For custom model names like gcp/google/gemini-2.5-flash, Vertex AI returned
404 because it only knows the actual model name (gemini-2.5-flash).
The fix makes the deployment lookup always run, so the custom model name
gets replaced with the actual Vertex AI model name before forwarding.
* add _resolve_vertex_model_from_router
* fix: get_llm_provider
* Potential fix for code scanning alert no. 4020: Clear-text logging of sensitive information

The regex in get_vertex_model_id_from_url() was using [^/:]+
which stopped at the first slash, truncating model names like
'gcp/google/gemini-2.5-flash' to just 'gcp'. This caused
access_groups checks to fail for custom model names.
Changed the pattern to [^:]+ to allow slashes in model names,
only stopping at the colon before the action (e.g., :generateContent).
