Root cause: WpWebhook called OutboundWorker::processQueue() after every
incoming message. BotRouter already sends synchronously in enqueueResponse();
failed messages stayed status='queued'. On the next incoming message
processQueue() would re-send ALL previously-failed messages, causing
the bot to repeat old responses.
- Remove OutboundWorker::processQueue() from WpWebhook::processEvent()
BotRouter handles immediate delivery; retries should be manual/cron only
- Fix chatSend(): instead of queuing + processQueue() (which drains ALL
queued messages), call WhatsAppSender::sendText() directly for the
one message being sent
