Initialize the contract with the trading pair and dependencies
Arguments:
admin: Admin address for contract management
pool: Blend pool address
margin_manager: MarginManager contract address
base_token: The base token of the pair (e.g., XLM)
quote_token: The quote token of the pair (e.g., USDC)

    admin: soroban_sdk::Address,
    pool: soroban_sdk::Address,
    margin_manager: soroban_sdk::Address,
    base_token: soroban_sdk::Address,
    quote_token: soroban_sdk::Address,
) -> Result<(), EntrypointError>

Update the margin manager contract address

fn set_margin_manager(
    env: soroban_sdk::Env,
    admin: soroban_sdk::Address,
    margin_manager: soroban_sdk::Address,
) -> Result<(), EntrypointError>

Get the pool address

fn get_pool(env: soroban_sdk::Env) -> soroban_sdk::Address

Get the admin address

fn get_admin(env: soroban_sdk::Env) -> soroban_sdk::Address

Get the margin manager contract address

fn get_margin_manager(env: soroban_sdk::Env) -> soroban_sdk::Address

Get the quote token address

fn get_quote_token(env: soroban_sdk::Env) -> soroban_sdk::Address

Open a LONG position on Base token
LONG Base = betting Base will appreciate vs Quote
Flow: Flash loan Quote → Swap Quote→Base → Supply Base as collateral → Borrow Quote → Repay flash loan
Result: Collateral=Base, Debt=Quote
Arguments:
caller: The user opening the position
flash_amount: Amount of Quote token to flash loan (also repay amount)
initial_margin: Amount of token the user provides as margin
collateral_amount: Amount of Base token to supply as collateral (for supply_collateral request)
collateral_from_base: If true, user provides Base token as margin.
collateral_amount = swap_output + initial_margin
borrow_amount = flash_amount (need full amount since margin is different token)
If false, user provides Quote token as margin.
collateral_amount = swap_output only
borrow_amount = flash_amount - initial_margin (margin helps repay flash loan)
swap_chain: Custom swap chain for multi-hop swaps. Empty Vec uses default direct swap.

fn open_long(
    env: soroban_sdk::Env,
    caller: soroban_sdk::Address,
    flash_amount: i128,
    initial_margin: i128,
    min_swap_output: i128,
    margin_from_quote: bool,
    swap_chain: soroban_sdk::Vec,
) -> Result<(), EntrypointError>

Open a SHORT position on Base token
SHORT Base = betting Base will depreciate vs Quote
Flow: Flash loan Base → Swap Base→Quote → Supply Quote as collateral → Borrow Base → Repay flash loan
Result: Collateral=Quote, Debt=Base
Arguments:
caller: The user opening the position
flash_amount: Amount of Base token to flash loan (also repay amount)
initial_margin: Amount of token the user provides as margin
collateral_amount: Amount of Quote token to supply as collateral (for supply_collateral request)
collateral_from_quote: If true, user provides Quote token as margin.
collateral_amount = swap_output + initial_margin
borrow_amount = flash_amount (need full amount since margin is different token)
If false, user provides Base token as margin.
collateral_amount = swap_output only
borrow_amount = flash_amount - initial_margin (margin helps repay flash loan)
swap_chain: Custom swap chain for multi-hop swaps. Empty Vec uses default direct swap.

fn open_short(
    env: soroban_sdk::Env,
    caller: soroban_sdk::Address,
    flash_amount: i128,
    initial_margin: i128,
    min_swap_output: i128,
    margin_from_quote: bool,
    swap_chain: soroban_sdk::Vec,
) -> Result<(), EntrypointError>

Reduce or close a LONG position on Base token
To reduce/close long (Collateral=Base, Debt=Quote):
Flow: Flash loan Base → Swap Base→Quote → Repay Quote debt → Withdraw Base collateral → Repay Base flash loan
Arguments:
caller: The user reducing the position
flash_amount: Amount of Base token to flash loan (will be swapped to Quote)
repay_amount: Amount of Quote debt to repay (expected output from swap)
withdraw_amount: Amount of Base collateral to withdraw (used to repay flash loan)
swap_chain: Custom swap chain for multi-hop swaps. Empty Vec uses default direct swap.

fn close_long(
    env: soroban_sdk::Env,
    caller: soroban_sdk::Address,
    flash_amount: i128,
    repay_amount: i128,
    withdraw_amount: i128,
    swap_chain: soroban_sdk::Vec,
) -> Result<(), EntrypointError>

Reduce or close a SHORT position on Base token
To reduce/close short (Collateral=Quote, Debt=Base):
Flow: Flash loan Quote → Swap Quote→Base → Repay Base debt → Withdraw Quote collateral → Repay Quote flash loan
Arguments:
caller: The user reducing the position
flash_amount: Amount of Quote token to flash loan (will be swapped to Base)
repay_amount: Amount of Base debt to repay (expected output from swap)
withdraw_amount: Amount of Quote collateral to withdraw (used to repay flash loan)
swap_chain: Custom swap chain for multi-hop swaps. Empty Vec uses default direct swap.

fn close_short(
    env: soroban_sdk::Env,
    caller: soroban_sdk::Address,
    flash_amount: i128,
    repay_amount: i128,
    withdraw_amount: i128,
    swap_chain: soroban_sdk::Vec,
) -> Result<(), EntrypointError>
