callebtc fc0e3fe663 Mint: watchdog balance log and killswitch (#705)
* wip store balance

* store balances in watchdog worker

* move mint_auth_database setting

* auth db

* balances returned as Amount (instead of int)

* add test for balance change on invoice receive

* fix 1 test

* cancel tasks on shutdown

* watchdog can now abort

* remove wallet api server

* fix lndgrpc

* fix lnbits balance

* disable watchdog

* balance lnbits msat

* test db watcher with its own database connection

* init superclass only once

* wip: log balance in keysets table

* check max balance using new keyset balance

* fix test

* fix another test

* store fees in keysets

* format

* cleanup

* shorter

* add keyset migration to auth server

* fix fakewallet

* fix db tests

* fix postgres problems during migration 26 (mint)

* fix cln

* ledger

* working with pending

* super fast watchdog, errors

* test new pipeline

* delete walletapi

* delete unneeded files

* revert workflows
