refactor: Move KSerializers to their respective NIP packages

- Bunker serializers → nip46RemoteSigner/kotlinSerialization/
- NIP-47 serializers → nip47WalletConnect/kotlinSerialization/
- Rumor serializer → nip59Giftwrap/rumors/kotlinSerialization/

Mirrors the existing Jackson serializer directory structure which uses
a jackson/ subpackage within each NIP package.
