System wide logs for debugging

[JoshCap20]

Logs on crucial aspects:

1. Communications (receipt, tickets)
2. Event registering and viewing
3. Guest ticket viewing

[JoshCap20]

Alternative:

• Fast DB that tracks views on an event (logs day, event viewed, user fingerprint). Uses: hot events, more analytics to event host, dashboard of event views.
• Definitely need communications logging, but should be added when we move communications to a separate server
• Guest ticket viewing is eh, we could just do similar tracks of ticket views in same fast DB as suggestion 1 on the new Rust server serving QR codes.
