fix(tools): move sandbox.tools import in view_image_tool to break circular import (#1674)
view_image_tool.py had a top-level import of deerflow.sandbox.tools, which
created a circular dependency chain:

  sandbox.tools
    -> deerflow.agents.thread_state (triggers agents/__init__.py)
      -> agents/factory.py
        -> tools/builtins/__init__.py
          -> view_image_tool.py
            -> deerflow.sandbox.tools  <-- circular!

This caused ImportError when any test directly imported sandbox.tools,
making test_sandbox_tools_security.py fail to collect since #1522.

Fix: move the sandbox.tools import inside the view_image_tool function body.
