[games] Create dedicated Twine game player template

[Abebes01]

We need to create a dedicated template for playing Twine games within our site, similar to how we handle embedded games. Currently Twine games just open in a new tab which provides a poor user experience compared to our embedded games. The template should render uploaded Twine games within an iframe on our site, include proper styling that matches our site design, and provide controls like fullscreen mode and back navigation. This will create a consistent gaming experience across all game types on our platform.
