WhatsApp automations now fail locally when they attempt to send a
free-form message after the 24-hour customer service window has closed.
This avoids sending an invalid template request to Meta and gives users
a clear, actionable error instead of “Template not found or invalid
template name.”
Template messages continue to be sent whenever template parameters are
present. Free-form messages continue to be sent normally while the
conversation is replyable.

### How to reproduce
1. Create a WhatsApp automation that sends a message without template
parameters.
2. Trigger it on a conversation whose 24-hour customer service window is
closed.
3. Observe that the message previously reached the template send path
and failed with a misleading provider error.
### How to test
1. Trigger an automation with template parameters and confirm it sends
as a template message.
2. Trigger an automation without template parameters inside the 24-hour
window and confirm it sends as a free-form message.
3. Trigger an automation without template parameters outside the 24-hour
window and confirm it fails locally with a clear error and makes no
request to Meta.
### Things to know
This changes only the invalid closed-window, no-template path. Existing
template and in-window message behavior remains unchanged.
