v1.1.2

Patch release: the CI pipeline now actually runs, plus the fixes it surfaced.

Fixed

• CI now triggers on master (was misconfigured to main, so it had never run).
• Backend: check the error from resp.Body.Close() in two places (errcheck).

Changed

• golangci-lint upgraded to v2.12.2 (golangci-lint-action@v9) with a migrated v2 config — required for Go 1.26.
• GitHub Actions bumped: checkout v7, setup-go v6, upload-artifact v7, docker/login-action v4, docker/build-push-action v7.
