Add option to control chat window opening direction (e.g. open to the left) Body:

[jwalli]

Hello Langflow team,

I would like to request a feature for the embedded chat widget:
Currently, the chat window always opens in one direction (to the right). It would be very helpful to have an option to control the opening direction of the chat window, for example, to allow it to open to the left when placed on the right edge of the screen.

Use case:
When the chat widget is positioned on the right side of the screen, it would be more user-friendly if the chat window opened to the left, so it remains fully visible and does not overflow off-screen.

Suggested solution:
Add a new attribute, such as open_direction="left" or similar, to the component, allowing developers to specify the direction in which the chat window should open.

Thank you for considering this feature!

Please use chat_position: "bottom-left" as an example.
