feat: add sanity-plugin-media + file fields + numbered statuses

- Install sanity-plugin-media for browsing all assets in Studio
- Add file type fields (audioFile, videoFile, shortFile) alongside URLs
  so media is previewable directly in Sanity Studio
- Pipeline now stores both file references and URLs on upload
- Status options now numbered (1-Draft through 6-Published) with
  descriptions for clarity in Studio
- Register media() plugin in sanity.config.ts
