backend/.golangci.yml declared version: "2" on line 1 but used the
golangci-lint v1 schema below it: a top-level linters-settings key and
an issues.exclude-use-default key that does not exist in v2. Under v2
that config does not validate, so every threshold in it was inert --
lll fell back to its 120-column default rather than the intended 88,
and funlen, cyclop and dupl were not applied at all. The `0 issues.`
result the repo has been relying on was therefore meaningless.

Replace it with the org-standard file verbatim (sha256
021cc83f4e6fc7c31b95b34b846723dfcf20b66b7baeea1dc40406e643346bcb) and
repoint the golangci-lint pin in Dockerfile.backend from v2.7.2 to the
org-standard v2.12.2.

Run `golangci-lint config verify` as the first step of the backend
lint target so this class of silent breakage fails the build in future
instead of degrading to default thresholds. It now runs everywhere
`make check` runs, including the pre-commit hook and the Docker build.

With the config actually loading, lll reports server.go:65 at 93
columns. Fix it, plus the two other over-long lines called out on the
issue (server.go:97 at 81 and reportbuf.go:166 at 88) which are inside
the 88-column lint limit but over the 77-column hard wrap in the Go
styleguide. All three were long //nolint justifications on the code
line; move the justification into a preceding comment block and leave
a short directive behind. No suppression is added or widened, and
.golangci.yml is not touched after the copy.

Verified: `cd backend && make check` reports `0 issues.`, root
`make check` passes, and `make docker` builds green against the pinned
v2.12.2.
