ci: silence errcheck on idiomatic Close/Rollback, gofmt two files

- .golangci.yml: exclude errcheck for (io.Closer).Close,
  (*os.File).Close, pgx Tx.Rollback, queue.Queue.Close, and
  net/http.ResponseWriter.Write. These are the "you can't recover
  anyway; logging the error is noise" cases — ~10 call sites in the
  tree would otherwise need nolint noise.
- pkg/db/sections.go, pkg/ingest/ingest.go: apply gofmt
  (struct-field alignment only).
