Sentry improvements: context, tracing, source maps, privacy manifest

- Set Sentry user context (id, username) in Journal root for all routes
- Tag Planner errors with session_id
- Use reactRouterV7BrowserTracingIntegration for route-aware traces
- Hidden source maps (no sourceMappingURL in bundles, .map deleted after
  upload to Sentry)
- Privacy manifest at /privacy documenting all data collection
- robots.txt blocking all bots on both apps
- Suppress i18next promotional console log
