Add a new AmountInput component to render an input field for entering
bitcoin denominated amounts. Has special handling for bitcoin / sats /
bits to ensure that only valid amounts can be entered and that the
formatting looks visually correct.
Make sure that if a user of ours is using neutrino that we flag their
channels as private when they manually open them. Reason for this is
because light consumer clients are not expected to have high uptime.
However we cannot hardcode channels as private every time because we
do support more power users driving their remote nodes or BTCPay
Server with Zap. So we only flag channels as private if the
activeConnection is local.
