make server automatically create DB schema if not exists (#5)

* add default values for CLI args

* add development docker compose file

* prevent crash if userdata dir does not exist

* accounts, acccountStats

* account stats and create db indices

* compensations and daily runs

* ensure uniqueness of daily seed

* start on port 8001 by default for client parity

* make generated schema match production

* sort imports
