fix(kanban): merge dashboard batch QOL with i18n + collapse + assignee-casing
PR #23240 was branched before main landed:
- c39168453 i18n localization (16 locales)
- a91e5a875 native <details> collapse + skip empty metadata
- 0e0ddaac8 tone down completed-run metadata panel
- b308dd7d7 preserve assignee casing in dashboard
The cherry-pick took PR's dist/index.js wholesale via -X theirs,
which dropped those features. This commit re-applies them by
hand-merging the 7 conflict regions:
1. bulk-action catch handler: keep PR's failedIds + loadBoard,
keep main's t-in-deps for tx() i18n calls
2. Refresh button: keep main's tx(t, 'refresh', ...), add PR's
Clear filters button with tx(t, 'clearFilters', ...)
3. Archive button: keep main's tx(t, 'archive', ...), add PR's
priority setter with tx(t, 'priority'/'setPriority', ...)
4. Column header: keep main's colHelp i18n var, add PR's
column-select-all checkbox
5/6. lane.tasks/column.tasks .map: keep main's t->tk rename
(avoids shadowing the i18n t), apply tk to PR's failed/
draggingSource props
7. Card checkbox label-wrap: keep PR's <label> structure
(larger hit target), keep main's tx(i18n, 'selectForBulk', ...)
Adds three new i18n keys (clearFilters, priority, setPriority)
that fall back to English via tx() until translators add them
to the kanban catalog, matching the existing pattern.
