perf: remove HTTP cache middleware, add service-level ETags

- Delete cache.rs middleware that buffered entire response bodies (up to 10MB)
  in RAM on every cache miss, defeating streaming and causing memory spikes
- Also buffered non-GET responses unnecessarily via response_map_body()
- Add lightweight ETag support (based on max modified_at + count) to:
  - FolderHandler::list_folder_listing (combined folder+files endpoint)
  - FileHandler::list_files_query (file listing endpoint)
- Both support If-None-Match / 304 Not Modified without any body buffering
- File downloads already had ETag/304 support at handler level
- Service-level caches (FileContentCache, SearchService, ThumbnailService)
  remain unchanged — they handle caching without HTTP body materialization
