* MM-68838: ping restored plugin remote immediately on re-register RegisterPluginForSharedChannels' restore branch updated the row but did not call PingNow, leaving the restored remote offline until the next pingLoop tick (up to PingFreq, default 1 minute). The new-connection branch already calls PingNow; the restore branch now mirrors it so sync attempts immediately after a plugin restart no longer fail with "offline remote cluster". * MM-68838: gob-encode error returns in apiRPCServer.ReceiveSharedChannelAttachmentSyncMsg The apiRPCServer wrapper for ReceiveSharedChannelAttachmentSyncMsg assigned the hook's error return directly to the gob-encoded response struct. When the framework's App.ReceiveSharedChannelAttachmentSyncMsg returned an error wrapped with %w (*fmt.wrapError, an unexported type), gob refused to encode it and the RPC server broke the connection with "type not registered for interface: fmt.wrapError". Every subsequent plugin/server RPC call then returned the zero-value response struct, causing plugins that dereferenced the nil returns to crash. Apply the existing encodableError() helper so the returned error becomes a gob-safe ErrorString, matching every other apiRPCServer method in this file.
