Bug Description

The Kanban dashboard throws a ReferenceError: COLUMN_LABEL is not defined when rendering column headers. The error occurs in plugins/kanban/dashboard/dist/index.js at line 1901, in the aria-label attribute of the "select all in column" checkbox.

The variable COLUMN_LABEL was renamed to FALLBACK_COLUMN_LABEL during the i18n refactor in commit c39168453 ("feat(i18n): localize all gateway commands + web dashboard, add 8 new locales"), but the reference at line 1901 was not updated to the new name.

Steps to Reproduce

1. Open the Kanban dashboard (/kanban tab in the Hermes dashboard)
2. The error fires at render time when the column checkbox input is mounted
3. Alternatively: click the checkbox to "select all tasks in column" — error fires at that point

Note: The error may not have surfaced in all setups depending on how the dashboard was initialized. The aria-label is not visually prominent and the error does not prevent the board from loading for most users.

Expected Behavior

Column headers render without JavaScript errors. The aria-label correctly reads: "Select all tasks in Triage" (or whatever the column name is).

Actual Behavior

ReferenceError: COLUMN_LABEL is not defined
    at render (plugins/kanban/dashboard/dist/index.js:1901:71)

The Kanban board still renders for most users since the error is in a non-critical aria-label attribute, but the error prevents the column select-all checkbox from functioning correctly and produces a console-level JS error.

Affected Component

• Other — Kanban dashboard plugin (plugins/kanban/dashboard/dist/index.js)

Root Cause Analysis

During the i18n refactor (commit c39168453), the top-level English dictionary COLUMN_LABEL was renamed to FALLBACK_COLUMN_LABEL to distinguish it from the new getColumnLabel(t, status) helper function. All call sites were updated — except one:

// Line 1901 — BROKEN (references old name)
"aria-label": \`Select all tasks in \${COLUMN_LABEL[props.column.name] || props.column.name}\`,

// Should be:
"aria-label": \`Select all tasks in \${FALLBACK_COLUMN_LABEL[props.column.name] || props.column.name}\`,

The same pattern was correctly fixed at other call sites (e.g., the column dot title attribute uses colHelp, the label text uses getColumnLabel(t, status)), but the aria-label was missed.

The downstream fix commit b8bf2f817 ("fix(kanban): merge dashboard batch QOL with i18n + collapse + assignee-casing") addressed other i18n hand-merge conflicts but did not catch this one.

Proposed Fix

One-line change in plugins/kanban/dashboard/dist/index.js line 1901:

-          "aria-label": \`Select all tasks in \${COLUMN_LABEL[props.column.name] || props.column.name}\`,
+          "aria-label": \`Select all tasks in \${FALLBACK_COLUMN_LABEL[props.column.name] || props.column.name}\`,

Debug Report

Note: hermes debug share captures server-side logs but not browser-side JavaScript errors from the dashboard plugin. The ReferenceError: COLUMN_LABEL is not defined is a client-side JS error that fires when the Kanban dashboard React bundle initializes in the browser.
