fix: use native fetch for getVideoBySlug to fix authenticated SSR

- Convert getVideoBySlug from Directus SDK to native fetch API
- Fixes serialization errors when authenticated users view video pages
- Remove unused readUsers import from @directus/sdk
- Directus SDK returns non-serializable objects with circular refs
- Native fetch returns plain JSON that works with SvelteKit SSR
