feat: add and distribute `chatIdentity.FirstMessageTimestamp` `FirstMessageTimestamp` enables members of the community to determine if there are any messages they can fetch on the community channel(chat). `FirstMessageTimestamp` is advertised by admin for each community chat through `CommunityDescription`. It assumes admin is online frequently enough to capture the first channel message. For existing communities admin determines first message timestamp by finding oldest chat message in its local database. task: status-im/status-desktop#6731
