fix(kanban): use colLabel for column select-all aria-label

[liuhao1024]

Summary

Fix ReferenceError: COLUMN_LABEL is not defined in the Kanban dashboard column select-all checkbox aria-label.

Root Cause

During the i18n refactor (commit c3916845), the top-level English dictionary COLUMN_LABEL was renamed to FALLBACK_COLUMN_LABEL, but the reference at dist/index.js:1901 was not updated. This causes a ReferenceError at render time when the column checkbox input is mounted.

Fix

Replace the undefined COLUMN_LABEL[props.column.name] with the already-computed colLabel local variable (line 1882), which goes through getColumnLabel(t, props.column.name) → tx() i18n fallback. This is the same pattern used by the column title span on the adjacent line.

Before:

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

After:

"aria-label": `Select all tasks in ${colLabel || props.column.name}`,

Testing

Verified that colLabel is computed on line 1882 via getColumnLabel(t, props.column.name) and is already used by the column title span. The aria-label now respects translations instead of always falling back to English.
