/api/v1/support/issue/{externalId}/comment

Appends a new comment to the ticket, attributed to the ticket reporter. Used by the reply form on the customer-facing ticket page on bizkithub.com. Applies min/max length, per-issue 24h rate limit, and an LLM spam check; spam replies are stored with a badge (or silently dropped once per-issue / per-IP thresholds are exceeded) and do not reopen closed tickets.
