- switched to `@tryghost/nql` packages to get access to latest releases
- updated `GET /members` mirage endpoint with a try/catch and explicit logging to make any errors from NQL more visible
- added "Name" filter option
- has `is`, `contains`, `does not contain`, `starts with`, `ends with` operators
- uses a plain text field for the input value
- added support for `~`, `-~`, `~^`, and `~$` operators when generating NQL queries from filter definitions
