change parsing priority for all passed arguments

update all passed args in server.js to prioritize command line, then use
env.UPTIME_KUMA_ environment variables, then use the generic environment
variable versions env.HOST, env.PORT, env.SSL_KEY, env.SSL_CERT and fall
back to default values where applicable
