feat: Integrate MinFeeVerifier and DaoScriptSizeVerifier into light-client

[Officeyutong]

This PR adds min fee check and DAO script size check when sending transactions through light client

• Every transactions submited to a light client by send_transaction will get their fee rate calculated, and compared to a pre-set fixed fee rate (1000 shannon per kilobytes). Transactions with insufficient fee rate will be rejected by send_transaction.
• Also, every transactions will be checked by DaoScriptSizeVerifier.

• [nitpick] Consider using an explicit conversion method instead of relying on into() here so that the intended type conversion for swc is clearer and more readable.

swc.clone().into(),

light-client-lib/src/tests/verify.rs:43

• Consider adding a test case to verify the error path when the transaction fee is below the minimum fee rate, ensuring that MinFeeVerifier::verify returns an appropriate error.

assert_eq!(fee_calculator.transaction_fee(&rtx).unwrap(), Capacity::shannons(1_0000_0000));
