feat: Enhance category management UX

Introduced a more interactive and user-friendly design on the categories
page by streamlining the content layout and adding a "Create category"
button. This improvement aims to make the management and organization of
VR projects more intuitive for users, facilitating easier navigation and
category creation. Additionally, new views for media upload and category
creation have been implemented, expanding the platform's functionality
and offering users more control over their content.

These changes are in response to user feedback requesting a more
organized and accessible way to handle categories and media within the
platform. By making these adjustments, we're enhancing the overall user
experience and laying the groundwork for future feature expansions.
