Sorting and exporting

Sort the list by name, role, role status, DBS expiry, or the expiry of any individual training module — the module list is built from whatever your own hierarchy actually holds. People with no date recorded always sort to the bottom, in both directions, so an unrecorded DBS never buries a genuinely urgent one. Export CSV downloads exactly what's on screen — same filters, same sort — with one row per leader and a column per training module, ready to open in Excel.
