feat: add merchant profile edit, keys dialog, and publish to Nostr

- Add PATCH endpoint for updating merchant profile config
- Add website field to MerchantProfile model
- Fix to_nostr_event to include all profile fields (display_name, banner, website, nip05, lud16)
- Always publish merchant profile (kind 0) when publishing to Nostr
- Extract edit-profile-dialog and nostr-keys-dialog into separate components
- Fix profile avatar alignment to match original design
- Simplify keys dialog to show only npub QR code (no nsec QR)
