feat: complete NIP-38 implementation with p tag, emoji, and expiration support

- Add optional r/p/e/a/emoji tags to StatusEvent.create() for full spec compliance
- Add GENERAL and MUSIC type constants to StatusEvent
- Filter expired statuses in UserStatusCache.addStatus() and add removeExpired()
- Add p tag (profile reference) display in DisplayStatusInner
- Add NIP-30 custom emoji rendering in status display via CreateTextWithEmoji
- Allow status type parameter in UserStatusAction.create()
