Local dev stack improvements

- Extend docker-compose.dev.yml with optional monitoring profile
  (Prometheus, Grafana, Loki) via --profile monitoring
- Align dev PostgreSQL with production: pg_stat_statements + init scripts
- Add scripts/seed.ts with idempotent Berlin test data (user, route, activity)
- Add pnpm db:seed and pnpm dev:reset scripts
- Simplify CI e2e job: replace manual docker run + BRouter setup with
  docker compose up --wait; add db:seed step
- Improve scripts/dev.sh: Docker check, --wait health checks, --monitoring
  flag, seed step
- Add scripts/reset-dev.sh to wipe and restart the local stack
- Add .env.development.example with documented local defaults
