[BUG] lnbits audit api - node balance fluctuates (not possible to rely on it e.g. custom implemented killswitch)

[gorrdy]

Describe the bug
Audit API sometimes returns different wallet balance (node_balance_msats) probably because a temporary channel down or ongoing HTLC or something

/admin/api/v1/audit

E.g. this could be a scenario when lnbits balance is greater than the node balance in 5 minutes
1:{'delta_msats': -45173146, 'node_balance_msats': 17033383, 'lnbits_balance_msats': 62206529}
2:{'delta_msats': -45173146, 'node_balance_msats': 17033383, 'lnbits_balance_msats': 62206529}
3:{'delta_msats': -45173146, 'node_balance_msats': 17033383, 'lnbits_balance_msats': 62206529}
4:{'delta_msats': -45190805, 'node_balance_msats': 17015724, 'lnbits_balance_msats': 62206529}
5:{'delta_msats': -45173146, 'node_balance_msats': 17033383, 'lnbits_balance_msats': 62206529}

This probably slows down the implementation of killswitch in LNbits? Is this a known issue?

If not it would be helpful to get the node balance in such way it is stable.

To Reproduce
Get the response of /admin/api/v1/audit and wait until the node routes the payment or there is a problem with a channel that goes off for some reason.

Expected behavior
Stable value of node_balance_msats
