feat: add relay rebroadcast settings for caching and propagation

- Add two new settings:
  - Use local relay(s) as cache (default: enabled)
  - Rebroadcast events to all relays (default: disabled)
- Create rebroadcastService to handle rebroadcasting events
- Hook into article, bookmark, and highlight fetching services
- Automatically rebroadcast fetched events based on settings:
  - Articles when opened
  - Bookmarks when fetched
  - Highlights when fetched
- Add RelayRebroadcastSettings component with plane/globe icons
- Benefits:
  - Local caching for offline access
  - Content propagation across nostr network
  - User control over bandwidth usage
