Also upgrades to node:22-alpine (current LTS) to clear the Node 20
deprecation warning on GitHub Actions.

Replaces localStorage with a JSON-file backend (server.js). Prayers are
stored in /data/prayers.json, which is mounted as a named Docker volume so
data survives container restarts and rebuilds. React fetches from /api/prayers.
