test: Refactor tests

- Move encoding integration tests to integration test folder (in the rust project)
- Move protocol integration tests be inside the protocol file. This way we can change the block without any problems and it is easier for integrators

/// Encodes a transaction for the Tycho Router using one of its supported swap methods.
///
/// # Overview
///
/// This function provides an **example implementation** of how to encode a call to the Tycho
/// Router. It handles all currently supported swap selectors such as:
/// - `singleSwap`
/// - `singleSwapPermit2`
/// - `sequentialSwap`
/// - `sequentialSwapPermit2`
/// - `splitSwap`
/// - `splitSwapPermit2`
///
/// The encoding includes handling of native asset wrapping/unwrapping, permit2 support,
/// and proper input argument formatting based on the function signature string.
///
/// # ⚠️ Important Responsibility Note
///
/// This function is intended as **an illustrative example only**. **Users must implement
/// their own encoding logic** to ensure:
/// - Full control of parameters passed to the router.
/// - Proper validation and setting of critical inputs such as `minAmountOut`.
/// - Signing of permit2 objects.
///
/// While Tycho is responsible for encoding the swap paths themselves, the input arguments
/// to the router's methods act as **guardrails** for on-chain execution safety.
/// Thus, the user must **take responsibility** for ensuring correctness of all input parameters,
/// including `minAmountOut`, `receiver`, and permit2 logic.
///
/// # Min Amount Out
///
/// The `minAmountOut` calculation used here is just an example.
/// You should ideally:
/// - Query an external service (e.g., DEX aggregators, oracle, off-chain price feed).
/// - Use your own strategy to determine an accurate and safe minimum acceptable output amount.
///
/// ⚠️ If `minAmountOut` is too low, your swap may be front-run or sandwiched, resulting in loss of
/// funds.
///
/// # Parameters
/// - `encoded_solution`: The solution already encoded by Tycho.
/// - `solution`: The high-level solution including tokens, amounts, and receiver info.
/// - `token_in_already_in_router`: Whether the input token is already present in the router.
/// - `router_address`: The address of the Tycho Router contract.
/// - `native_address`: The address used to represent the native token
///
/// # Returns
/// A `Result<Transaction, EncodingError>` that either contains the full transaction data (to,
/// value, data), or an error if the inputs are invalid.
///
/// # Errors
/// - Returns `EncodingError::FatalError` if the function signature is unsupported or required
/// fields (e.g., permit or signature) are missing.
