fix: correct indentation issue in PythonCodeStructuredTool and correct type for int and float inputs when updating custom component (#3323)

* enhancement: Update PythonCodeStructuredTool to create inputs automatically and accept global variables

* [autofix.ci] apply automated fixes

* feat: Create a tool to search using SearXNG

* [autofix.ci] apply automated fixes

* refactor: reorganize imports and type annotations in PythonCodeStructuredTool.py for clarity and consistency

* refactor: clean up imports and enhance type annotations in SearXNGTool.py for improved readability and type safety

* refactor: Improved PythonCodeStructuredTool to allow arguments to have any types

* refactor: Formatted and refactored SearXNGTool

* refactor: Allowed RunnableExecutor to stream output and changed its build method to asynchronous.

* fix: correct indentation issue in PythonCodeStructuredTool

* fix: correct type for int and float inputs when updating custom component

* [autofix.ci] apply automated fixes

* fix: change Tool to StructuredTool due to arguments in SearXNGTool

* refactor(endpoints.py): remove duplicate imports of loguru and sqlmodel to improve code readability and maintainability
