Added `background_image_url`, `foreground_image_url`, and `asset_image_urls` fields to enhance theme customization. Updated `asset_image_urls` to use `MutableDict` with a default empty dictionary and ensured consistency in the model and migration script.
The `is_active` field was introduced to the `EventTheme` model to indicate whether a theme is active. The corresponding test fixture in `conftest.py` was updated to include this new field, ensuring consistency in tests. This change enhances flexibility for managing event themes.
Updated the schemas and models to make `last_name` optional and set a default value of "user" for `first_name`. This change enhances flexibility for user data handling and ensures proper defaults when values are not provided.
This migration introduces all initial database models and their respective tables, relationships, and constraints. It includes entities such as users, events, guests, themes, media, and various related entities to support application functionality. This serves as a foundational schema for the project.
