Description
This PR implements the backend proxy and transaction assembly service for the AutoShare Soroban contract (Closes #125).
Because the backend server never holds a user's secret key, it cannot directly sign Soroban smart contract invocations. Instead, we've implemented a robust "prepare-sign-submit" lifecycle where the backend acts as an RPC gateway: it simulates the transaction, calculates fees, assembles the XDR, and relies on the frontend client for wallet signatures before safely submitting the transaction back to the network.

Following this merge, the frontend interface can be updated to consume
/prepare, sign the XDR payload with Freighter, and push to/submit.
