lnworker: use config lightning fee for estimate

I was unable to do a "Max" amount submarine swap because the
`fee_estimate` function used by `LNWallet.num_sats_can_send()` uses a
hardcoded `fee_proportional_millionths` to estimate the fee for the
lightning payment. When the actual fee determined later is higher
than the estimated fee the payment fails as the channel is unable to add
the htlc sum including the real fees as the amount exceeds what the
channel can add.
Using `SimpleConfig.LIGHTNING_PAYMENT_FEE_MAX_MILLIONTHS`
seems more reliable here as it will always use the true maximum fee
the user is willing to pay for the fee estimate.
