- Changed the build process to include a web UI build stage using Node.js. - Updated Go build stage to copy web UI files to the correct location. - Removed the main.go file as it is no longer needed. - Added SQLite database configuration to example config. - Updated dependencies in go.mod and go.sum, including new packages for JWT and SQLite. - Modified .gitignore to include new database and configuration files.
