fix: deduplicate cloud media in search and location flows + cleanup MediaViewScreen

- Add deduplicateCloudLocal() to remove cloud duplicates when a local counterpart
  with matching cloudGroupKey exists in search results and location data
- Remove unused Configuration/LocalConfiguration imports and simplify landscape
  padding logic in MediaViewScreen
