Add production API config to eink-scheduler and disable service by default

- Disable eink-scheduler service by default to prevent board from sleeping too quickly during development/testing
- Add production API configuration section to eink-scheduler.conf.example
- Development API (api.dev.e-tabelone.com) is active by default
- Production API (api.e-tabelone.com) is commented out for easy switching
- Configuration file includes both dev and production settings directly in the file
