Refactor Plex account linking process and update user interface

- Removed the display of the PIN code in the user interface and replaced it with a direct link to the Plex authentication URL, enhancing user experience.
- Updated instructions for linking a Plex account to reflect the new authentication flow.
- Modified the backend logic to utilize a database for storing Plex account information, improving data management and error handling.
