Muhsin Keloth 7e8fe78ecd perf: Add database index on conversations identifier (#12715) ...

**Problem**
Slack webhook processing was failing with 500 errors due to database
timeouts. The query `Conversation.where(identifier:
params[:event][:thread_ts]).first` was performing full table scans and
hitting PostgreSQL statement timeout.

**Solution**
Added database index on conversations.identifier and account_id.
