* feat: Integrate Jupiter DEX * feat: Enable internal swaps * feat: implement Jupiter swap execution api and enhance trade handling - Added executeSwap method to handle signed swap transactions via the execute endpoint. - Updated signAndPrepareJupiterSwapTransaction to include request ID and handle swap execution response. - Modified trade details to use txId instead of id for Jupiter trades. - Enhanced error handling for swap execution with user-friendly messages. - Updated sendviewmodel to manage trade state updates after transaction commitment. * fix: null error after successfully swapping * fix: Finallyyy fixed the annoying tx history issue for solana dex swaps * fix: update inputAddress to use toAddress in JupiterExchangeProvider * feat: enhance transaction handling and token balance updates - Cut down tx fetch/update time for transactions update after swapping - Added TransactionFetchResult class to hold parsed transactions and token mints. - Added pollForTransaction method to handle transaction polling with exponential backoff. - Conditionally hide the external send button based on provider type. * feat: add fees to trade object and handle null case * feat: add Jupiter referral fee and account configuration --------- Co-authored-by: Omar Hatem <omarh.ismail1@gmail.com>
