refactor: consolidate debug flag and update gitignore

- Rename debugMode to isDebug for consistency across codebase
- Move debug flag check in ValidateTimeStamp to match other validations
- Add database.db to gitignore and remove unused config file
- Update README.md to clarify user registration rules
