chore: rename UI Tochka→Bank, prod-ready compose, init migration, Caddy snippet

- UI nav: Точка → Банк (route /bank), label-only — internal Tochka API module unchanged
- compose: drop our own Caddy (queoserver uses host-level Caddy), web-nginx proxies /api/*+/webhooks/* to api:3030 internally; expose only 127.0.0.1:3031
- Dockerfile.api: simpler single-stage with tsx for prod (avoids dist build complexity)
- prisma/migrations/0_init committed via `prisma migrate diff` for `migrate deploy` in prod
- docker/Caddyfile.snippet: copy-paste block for queoserver's /etc/caddy/Caddyfile
- .gitignore: data/ (covers embedded-pg, postgres, caddy data dirs)
