backend-ci.yml's `test -z "$(gofmt -l .)"` strict gate (added in
13c21ac11) failed on a backlog of unformatted files. None of the
85 files in this commit had been edited since the gate was added
because no push touched veza-backend-api/** in between, so the
gate never fired until today's CI fixes triggered it.
The diff is exclusively whitespace alignment in struct literals
and trailing-space comments. `go build ./...` and the full test
suite (with VEZA_SKIP_INTEGRATION=1 -short) pass identically.
