fix(lint): clear the two findings left by #69 and #70 (#72)

- observation_update_test.go (#69) lacked the fts5 build tag its helper
  (testObservationStore, in observation_store_test.go) has, so `go vet ./...`
  without tags failed with "undefined: testObservationStore".
- Client.knn (#70) concatenates its WHERE clause into the query. The clause is
  built only from constant text with "?" placeholders (see nearest) and every
  value goes through args, so gosec's G202 is a false positive; annotate it the
  way the file already annotates G201.
