Close leveraged margin position

[djeck1432]

You will create the main part of contract logic by implementing close_position function, where we will put the debt token back in our pool and return to the user part they earned.

• Check position is open
• Write position as closed in the storage, save the needed values for later use in the current function
• Add debt amount to the debt token pool
• Swap debt amount on Ekubo using exact-output swap(from traded_token to debt_token)
• Transfer to the user initial_amount + traded_amount - swapped_amount of the base token they opened position with
• Write tests and docstrings

please let me take on this, I will implement the close_position function, ensuring proper position validation, debt repayment, token swaps on Ekubo, user fund returns, and storage updates. I will also write tests and documentation.
