Introduces models for events and their themes, including fields for event details, location, timing, and settings. The `EventTheme` model supports theme customization with color palettes and fonts, while establishing relationships with the `Event` model. These additions prepare the database for event-related functionality.
Created reusable `Base`, `UUIDMixin`, and `TimestampMixin` in `base.py`. Added a `User` model with attributes, relationships, and database configurations in `user.py` to establish a foundation for user-related features.
This commit includes configurations and boilerplate code for both frontend and backend. The frontend uses Next.js with Tailwind CSS, while the backend is built with FastAPI. Various essential files like `tsconfig.json`, `requirements.txt`, and `.gitignore` have been added to kickstart the development process.
