fix(dashboard): GIT filter shows i18n labels matching table display

Filter dropdown showed raw backend tokens ('no_repo', 'diff') while
table cells showed i18n labels ('НЕТ РЕПО', 'ЕСТЬ ИЗМЕНЕНИЯ').

- Add getFilterOptionLabel() to DashboardsFiltersModel for label mapping
- Add getLabel prop to ColumnFilterPopover for display/value separation
- Delegate getFilterOptionLabel through DashboardHubModel
- Raw tokens remain as filter values (backend compatible)
- Labels rendered via getLabel in filter dropdown
