What does this PR do?

Fixes a Kanban dashboard render crash caused by a stale COLUMN_LABEL reference in the column select-all checkbox aria label.

The dashboard now computes colLabel through getColumnLabel(t, props.column.name), which supports the current i18n fallback path. Reusing that value avoids referencing the removed COLUMN_LABEL object and keeps the accessible label aligned with the rendered column title.

Before this change, opening the Kanban dashboard could fail with:

ReferenceError: COLUMN_LABEL is not defined

Fixes #23620.

Changes Made

• plugins/kanban/dashboard/dist/index.js
  • Replaces the stale COLUMN_LABEL[props.column.name] lookup with the already computed colLabel fallback for the select-all checkbox aria-label.

How to Test

1. Start the dashboard and open the Kanban tab.
2. Confirm the board renders instead of showing the plugin render error.
3. Confirm the column select-all checkboxes have accessible labels such as Select all tasks in Triage.
4. Run validation commands:

node --check plugins/kanban/dashboard/dist/index.js
python -m pytest tests/plugins/test_kanban_dashboard_plugin.py -q -o 'addopts='

Validated locally:

node --check plugins/kanban/dashboard/dist/index.js
# no output, exit code 0

python -m pytest tests/plugins/test_kanban_dashboard_plugin.py -q -o 'addopts='
# 81 passed
