watcher: change messages name only the record types that differ (closes #219)

A Record Change notification printed the nameserver's whole old and new record sets in Go map syntax, and an Inconsistency notification the two nameservers' whole sets, so a one-address change had to be found by eye among kilobytes of unchanged TXT, CAA, MX and NS values. Both now list, in sorted order of type, only the record types whose values differ: a line naming the type, then each side's values separated by commas, or none when that side has no records of that type. The dashboard's Recent alerts shows the same text. Model: opus-5-5
