Fix: Ensure hashtag interests drive the video feed engine

Updated `NostrClient.subscribeVideos` to accept dynamic tags for filtering.
Integrated `HashtagPreferencesService` into `NostrService` to refresh the video subscription whenever user interests change.
This ensures the main video feed correctly reflects the user's selected hashtags by fetching matching content from relays.
