feat: migrate feed views to composite components with slot support

- Add feed.composites.tsx with createFeedTimelineComposite and createFeedDetailComposite - Timeline and detail views now use CompositeComponent with renderActions slot - Admin actions wired through slots for client-side interactivity - Table view retains contentRsc approach (too interactive for composites) - Simplify feed.$id route by moving shell markup to server composite
