Fix okx tx issue

[Julian-dev28]

This pull request updates the OKX provider integration in the packages/swap/src/providers/okx/index.ts file to enhance compatibility with Solana transactions, improve API request handling, and add better debugging and error handling. The most important changes include switching to legacy Solana transactions, updating API endpoints, refining parameter handling for quotes and swaps, and introducing a new method to process OKX transaction data into valid Solana transactions.

Enhancements to Solana transaction handling:

• Changed the transaction type to legacy to accommodate OKX's custom instruction data, as opposed to standard Solana transactions.
• Added a new method, createSolanaTransactionFromOKXData, to convert OKX transaction data into valid Solana transactions, ensuring proper deserialization, fee payer updates, and blockhash assignment.

API endpoint updates:

• Updated the OKX API base URL and endpoint paths for tokens, quotes, and swaps to align with the new API structure.

Improvements to parameter handling:

• Adjusted quote parameters to exclude unnecessary fields and conditionally include feePercent only when valid (greater than 0 and less than or equal to 10).
• Refined swap parameters to ensure proper handling of native and wrapped SOL addresses, added required fields like autoSlippage, and conditionally included fee-related fields.

Debugging and logging enhancements:

• Added detailed debug logs for quote and swap parameters, as well as for the process of converting OKX transaction data to Solana transactions, to aid in troubleshooting and validation. [1] [2]
