Add self-hosted Umami analytics to replace the third-party cloud.umami.is
tracker. Creates @harb/analytics package with typed event helpers and
instruments the conversion funnel: CTA clicks (landing), wallet connect,
swap initiated, and stake created (web-app).
- Add Umami Docker service sharing existing postgres (separate DB)
- Add Caddy /analytics route to proxy Umami dashboard
- Configure via VITE_UMAMI_URL and VITE_UMAMI_WEBSITE_ID env vars
- Document setup and funnel events in docs/ENVIRONMENT.md

## Summary
- add a useSnatchSelection composable that centralises snatch shortfall calculations, position filtering, and RPC memoisation
- refactor StakeHolder.vue to consume the composable instead of reimplementing the flow inline
- introduce Vitest config and first composable tests (useSnatchSelection.spec.ts) to cover empty/partial fills and ownership edge cases
- wire up project tooling updates so the new tests run (jsdom dep, updated package metadata)
## Testing
- cd web-app && npm install
- npm test
