fix: send non-JPEG images as document instead of photo; fix Dockerfile home.html path

- getFileType: only classify image/jpeg as 'photo'; png/gif/webp → 'document'
  (Telegram Bot API rejects non-JPEG for sendPhoto)
- Dockerfile: copy home.html to dist/ instead of root (import.meta.dir = dist/)
- Update test assertion for getFileType(image/png) → 'document'
