[lib] reduce thread updates from createOrUpdateFarcasterChannelTag an…

…d deleteFarcasterChannelTag

Summary: Depends on D13779

Test Plan:
tested setting and unsetting community tags from a client running an older code version and it worked as expected -- no crashes, communities and threads tables updated on keyserver. eventually the state check mechanism synced the client threads with the keyserver

tested the same thing on a new client that can receive the thread changes directly and confirmed that the actions were reduced correctly and the redux state thread info looked right
