fix: glitchtip performance metrics + cleanup test submissions

- Refactor GlitchtipErrorReportingService to support dynamic DSN and tracesSampleRate
- Enable client-side performance tracing by setting tracesSampleRate: 0.1
- Configure production Mail variables and restart containers on alpha.mintel.me
