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 and checked its certificates twice, sending two expiry warnings per TLS check (port checks were already grouped by address and port). 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
