Add Loading component and use across views

Introduce a reusable Loading component (src/components/ui/loading.tsx) that shows a spinning Loader2 icon and an optional message. Replace ad-hoc loading UIs by importing and using Loading in BrowseView and CastView. In App.tsx, add mediaLoading state (set around fetchAllMedia) and pass it to BrowseView; also add local loading states to MediaDetailRoute and CastDetailRoute to show Loading while fetching details. These changes centralize loading UX and remove duplicated spinner markup.
