fix: correct useProfile usage and ProfileContent handling in ZapWindow

- Remove eventStore argument from useProfile (takes pubkey and optional relay hints)
- Fix recipientProfile usage: already ProfileContent, don't call getProfileContent again
- Fix authorProfile: call getProfileContent on NostrEvent, not on ProfileContent
- Fix lud16/lud06 access: use recipientProfile directly
- Fix success toast: use recipientProfile?.name instead of content?.name

All type errors resolved. ProfileContent is returned by useProfile, not NostrEvent.
