refactor: move data.db and uploads to storage/ folder

- Changed database path to ./storage/data.db
- Changed uploads path to ./storage/uploads
- Updated Dockerfile to create storage/uploads dir (not uploads)
- Updated entrypoint.sh to check /app/storage/data.db
- Removed COPY of uploads from builder to runner

Now all persistent data is in /app/storage/:
- /app/storage/data.db (SQLite database)
- /app/storage/uploads/ (uploaded media)

Easypanel mount: emdash-storage → /app/storage

To update EmDash: change version in package.json → push → redeploy
