WHS list pages converted to data tables

Every workplace health and safety list page now uses the same fast, sortable, filterable DataTable as the rest of the platform.

## Improvement — WHS lists rewritten

Incidents, hazards, corrective actions, inspections, return-to-work plans and every workers' compensation sub-list (appeals, assessments, benefits, documents, medical certificates, audit trail) now use the standard DataTable component — checkbox bulk actions, drag-and-drop column reorder, sticky header, server-side pagination, sortable columns and per-row action menus.

Status badges across the WHS module now use the same light-tinted bordered style as everywhere else in the app, replacing the old heavy fill.
