1. Description of the Feature Request: While a lot of channel/member ID's are already stored in config.js, they are usually still hardcoded in the reply strings. Changing them to instead import and interpolate them has 2 advantages: in the unlikely but possible event a channel gets deleted and recreated there is one source of truth to change, and more importantly <#${channels.FAQChannelId}> is a lot clearer to read at a glance than something like <#823266307293839401>

2. Acceptance Criteria:

• [ ] All ID's which are currently not present are added to config.js
• [ ] All reply strings use imported and interpolated strings where possible
