fix: remove sponsor mention + add Nostr preview modal before publishing

- "Sponsors see the organic number" -> "Users can now see both numbers"
- PublishToNostrButton now opens a preview modal first (NostrPreviewModal):
  - Mock Nostr post card: avatar, display name, timestamp, post body
  - nostrText rendered with hashtags in blue and URL underlined
  - Fake engagement bar (replies/reposts/zaps at 0) for visual context
  - Character count shown below the card
  - Two actions: "Edit first" (closes modal) / "Publish" (confirms)
  - Full-width on mobile, correct safe-area handling via Dialog component
  - isPending state flows through so button shows "Publishing..." while signing
