feat: Implement API routers for user, tag, vas, webdav, and slave functionalities

- Added user authentication and registration endpoints with JWT support.
- Created tag management routes for creating and deleting tags.
- Implemented value-added service (VAS) endpoints for managing storage packs and orders.
- Developed WebDAV account management routes for creating, updating, and deleting accounts.
- Introduced slave router for handling file uploads, downloads, and aria2 task management.
- Enhanced JWT utility functions for token creation and secret key management.
- Established lifespan management for FastAPI application startup and shutdown processes.
- Integrated password handling utilities with Argon2 hashing and two-factor authentication support.
