feat(EventMenu): add relay hints to Copy ID feature (#44)

Enhance the Copy ID feature in the event menu to include relay hints
from where the event has been seen. This improves event discoverability
by providing clients with relay suggestions when decoding nevent/naddr.

Changes:
- Import getSeenRelays from applesauce-core/helpers/relays
- Update copyEventId to retrieve seen relays for the event
- Pass relay hints to both neventEncode and naddrEncode
- Follows the same pattern as EventDetailViewer

Benefits:
- Better event sharing with relay context
- Helps other clients find events more easily
- Improves NIP-19 identifier quality
