Fix deployment documentation and scripts for TypeScript setup

- Update deployment instructions to properly compile TypeScript
- Fix systemd service to run dist/server.js instead of server.js
- Standardize on /opt/icewatch as installation directory
- Change icewatch user to have bash shell for easier management
- Add explicit database creation steps
- Create quick deployment guide for simplified setup
- Update README with corrected deployment steps
- Fix all references from various names to consistent 'icewatch'

This ensures the /table route and all TypeScript features work correctly
after deployment by running the compiled JavaScript output.
