Update template by id

Update one variant's components and/or its message_send_ttl_seconds by its Meta id. Name, language and category cannot change.

Meta only allows editing templates in APPROVED, REJECTED or PAUSED state; an approved template can be edited once per 24 hours and up to 10 times per 30 days. A component update sends the variant back to Meta for review, so the status returned here is normally PENDING; a TTL-only update keeps an APPROVED variant approved. The final outcome arrives on the whatsapp.template.status_updated webhook (which carries the variant's templateId and language). A variant already in PENDING cannot be edited again until Meta finishes reviewing it.
