feat: add Docker support and fix page refresh issues

- Add Dockerfile with root user for simplified deployment
- Add docker-compose.yml for local development
- Add docker-compose.prod.yml for production deployment
- Add start.sh script for container initialization
- Fix page caching: add dynamic rendering to all pages
- Update database initialization to handle permissions
- Update README with deployment instructions

This is the first fully functional version with Docker support.
No manual permission setup required on deployment.

 The easiest way to deploy your Next.js app is to use the [Vercel Platform](https://vercel.com/new?utm_medium=default-template&filter=next.js&utm_source=create-next-app&utm_campaign=create-next-app-readme) from the creators of Next.js.
 
 Check out our [Next.js deployment documentation](https://nextjs.org/docs/app/building-your-application/deploying) for more details.

+## Deploy locally with docker compose, and push to remote
+
+### Build and push new image
+```bash
+# Build the image
+docker compose build
+
+# Tag for registry
+docker tag battery_tracker-battery-tracker:latest 192.168.2.212:3000/tigeren/batterytracker:1.0
+
+# Push to registry
+docker push 192.168.2.212:3000/tigeren/batterytracker:1.0
+```
+
+### Deploy on a new server
+
+**Simple deployment - no manual permission setup needed!**
+
+```bash
+# 1. Copy docker-compose.prod.yml to your server
+
+# 2. Pull and start (the container runs as root and handles permissions automatically)
+docker compose -f docker-compose.prod.yml pull
+docker compose -f docker-compose.prod.yml up -d
+```
+
+The database file will be automatically created at `./data/battery_tracker.db`
