Part of #12466 (the separate "Up to date (6)" mislabel noted there). Siblings: #12472 (spoke loop), #12474 (×0 badge).

Problem

Grouping /dashboard by Upgrade state showed an "Up to date (6)" header over six hives whose rows each read "107–161 behind". hiveUpgradeState returns '' for "no rollout in flight and nothing queued", and the grouper mapped every '' to "Up to date" — including hives far behind with auto-upgrade off or whose tracked channel has not promoted.

Fix

• New named grouper hiveUpgradeGroupLabel(h) (the dimension's of() now delegates to it): queued → upgrading → Behind target (no upgrade pending) when commitsBehindTarget > 0 → Up to date.
• New HIVE_UPGRADE_GROUP_BEHIND constant; _upgradeGroupOrder sorts it between Upgrading and Up to date; unknown labels still last.
• hiveUpgradeState itself is unchanged, so the filter pills / facet counts / row badges keep their contract.

Tests

• TestUpgradeGroupLabelSplitsBehindFromUpToDate (node harness on the real JS: current / behind+off / behind as string / queued / upgrading, plus sort order) and TestUpgradeGroupDimensionUsesNamedLabeler.
• go test ./pkg/hub/... ./pkg/dashboard/... -count=1 green; no new inline style=.

Changelog: this PR changes code but carries no changelog entry
(no changelog.d/ fragment and no CHANGELOG.md edit).

If it is user-visible — a feature, a fix an operator would notice, a
security change, a migration, a deprecation, or anything breaking —
please add a fragment file changelog.d/<category>-<pr-or-slug>.md
containing exactly your entry (see changelog.d/README.md; the
category is one of added/changed/deprecated/fixed/security). Please
do not append to CHANGELOG.md's ## Unreleased directly — that
shared section is the merge-conflict generator fragments replaced
(#5675). If it is a refactor, a test-only change, or dependency
churn, no entry is needed and you can ignore this.

This is a reminder, not a gate; it never blocks a merge.

Changelog fragment in the wrong directory

Fragments live in changelog.d/ at the repository root, not under src/. Files under src/changelog.d/ are never compiled into CHANGELOG.md, so the changelog-fragment-guard check fails. Move them and push:

git mv src/changelog.d/fixed-hub-upgrade-group-behind.md changelog.d/fixed-hub-upgrade-group-behind.md
git commit -s -m "changelog: move fragment to repo-root changelog.d/"

See changelog.d/README.md (#5675, #11919). This comment is removed automatically once nothing is misplaced.
