* Add a `webRoot` property to the config file to override the web UI used
* Allow all config options to be set via env variables
* Fix TS
* Fix test file paths
* Move “Listening on” message to after we’re actually listening
* Fix codeql warning
* Fix bug when config.https is null but HTTPS_* env vars are defined
* Allow passing raw key/cert into `https.key`/`https.cert`
* Allow passing config file as ACTUAL_CONFIG_PATH
* Forgot to handle userConfig not being specified
- code as written expects the file may be absent and has a fallback
implemented, so the error can be safely ignored. There may be a better
strategy for dealing with this, however.
