- group/lab/labs: move dialogs/scripts INSIDE the #content fragment (they were
outside — the layout fragment dropped them, which is why 'add student' did nothing)
- group.html toast had swallowed the dialog (th:if createdStudent) — split properly
- .input-score width no longer overridden by .inline-form .input-sm (10rem min)
- lab page: remove separate 'change status' button — status badge is now a toggle
button itself (confirm dialog kept)
- DateUtils.localInput/toUtcIso: dates entered in datetime-local are Moscow-local,
stored as UTC instant, shown back MSK — correct round-trip both ways
- academic parseInstant: naive local datetimes treated as Europe/Moscow
- README/module docs left as-is
