/starknetTokenIncreaseAllowance

Increases the allowance granted to a specific address (spender) for an ERC20-compatible token on Starknet. This function safely adds to the existing allowance amount rather than replacing it entirely, providing better security against race condition attacks that can occur with the standard approve function.

The increase_allowance pattern is considered a security best practice for managing token approvals. Instead of setting a new absolute allowance amount (which could be exploited in edge cases), this function adds the specified amount to whatever allowance currently exists, ensuring predictable and secure behavior.

This function is particularly useful for DeFi applications where users need to grant incremental spending permissions to smart contracts, or when managing allowances for automated trading systems that require periodic allowance increases without completely resetting approval amounts.

This function internally calls sendTransactionToStarknetContractWithContractInfo with the "increase_allowance" function and properly formatted parameters, following Starknet's ERC20 interface specification.

Return: JSON object with the transaction submission result with approval status and transaction details.
