fix: replace bare raise with ToolUsageError in _original_tool_calling (#6430)

[fazalpsinfo-cmyk]

Description

A bare raise in _original_tool_calling() at line 853 is outside any exception handler. When arguments is not a dict, this causes RuntimeError: No active exception to re-raise instead of a meaningful error.

Fix

Replaced the bare raise with raise ToolUsageError(...), matching the error path that already exists in the non-raise branch.

Closes #6430
