feat: integrate Electron for desktop application support

- Added Electron entry point in `electron/main.js` to run the Express server in-process and open the main application window.
- Updated `package.json` to include Electron dependencies and scripts for building and running the application.
- Refactored server startup logic into `server/start.js` for better modularity and to support both CLI and Electron usage.
- Implemented environment variable handling for database and image paths to accommodate Electron's packaging.
- Created a script `server/scripts/promote-morphix.js` to merge admin and morphix accounts into a single user.
- Adjusted image root path resolution in `server/media/images.js` to allow for environment variable overrides.
- Cleaned up `server/index.js` to delegate server initialization to the new `startServer` function.
