Problem

TestValidator can be created with custom specified target_lamportds_per_signature

    pub fn with_custom_fees(
        mint_address: Pubkey,
        target_lamports_per_signature: u64,
        faucet_addr: Option<SocketAddr>,
        socket_addr_space: SocketAddrSpace,
    ) -> Self 

Cli tests uses with_custom_fees() but with target_lamports_per_signature == 1. This works accidentally because calculate_fee() currently uses fee_structure's default lamports_per_signature so long fee_rate_governor.lamport_per_signature <> 0.

Calculate_fee() is going to change (eg. be corrected). But in any case, cli tests should use correct value in setting up TestValidator.

Summary of Changes

• setting up TestValidator with correct target_lamports_per_signature
