feat: add chat/comments action to all event types in menu

The event menu now shows a chat action for all event types:
- Kind 1 notes: Opens NIP-10 thread chat (labeled "Chat")
- All other events: Opens NIP-22 comments (labeled "Comments")

For addressable events (articles, live activities, etc.), uses address
pointer. For regular events, uses event pointer with relay hints.
