config: watch a target listed twice only once (closes #207)

ClassifyTargets kept a name every time it appeared in DNSWATCHER_TARGETS, so example.com,Example.com. put example.com in the domain list twice and every check looked it up, checked its ports and its certificates twice, sending two expiry warnings per TLS check. It now skips a name it has already kept, comparing after the lower-casing and trailing-dot removal it already did; the list keeps the order of first appearance. Model: opus-5-5
