feat: Implement Dioxus fullstack application

This commit introduces a full-stack Dioxus application with a web frontend to manage TTRPG data from a SQLite database.

The application is built using a Server-Side Rendering (SSR) architecture with Axum for the web server and Dioxus for templating. This approach was chosen for its simplicity and robustness, avoiding client-side build complexities.

Features include:
- A web server powered by Axum.
- Server-side rendered pages for Home, Creatures, Edit Creature, Import, and Changelog.
- Database integration with `sqlx` to view a list of creatures and details for a single creature.
- A modular structure with components, pages, and database logic separated into modules.
- A navigation bar for easy access to all pages.
- Placeholder pages for data import and editing functionality.
