Open leveraged margin position

[djeck1432]

You will create the main part of contract logic by implementing open_margin_position function, which allows our users to use our pools to open bigger positions.

• Verify that tokens provided by user are on Pragma, validate allowance and amount, check that tokens have different addresses. User can't have more than one active position at once.
• Calculate how much our user needs to borrow from our pools using appropriate internal function, if this amount is bigger than we have in our pools, throw an error.
• Take calculated amount from the pool by subtracting it from the correct storage entry.
• Transfer token from the user
• Swap calculated amount on Ekubo
• Write Position structure to the storage
• Add reentrancy guard
• Write tests and docstring

i will love to take on this, I will implement the open_margin_position function, ensuring proper validation, borrowing logic, token transfers, swaps, and storage updates while securing it with a reentrancy guard. I will also write comprehensive tests and documentation.
