Sweep task 5 (Shared/Drivers + Acls):
- btn-group the Save/Cancel pair in DriverFormShell (all 13 driver forms),
CollectionEditor foot + per-row Edit/Delete, DriverConfigModal /
DeviceModal / DriverTagPicker / AclScopePickerModal feet,
DriverStatusPanel Reconnect+Restart and its inline restart confirm,
and the Refresh+Close browse toolbars on the FOCAS/AbCip/TwinCAT pickers.
- Replace the no-op inline border-color:var(--alert) tint with .notice-alert
in DriverFormShell, DriverConfigModal, DeviceModal, MqttDriverForm,
MTConnectDriverForm, MqttDeviceForm.
- Replace inline style="width:18px" expander sizing with .tree-twist in
DriverBrowseTree and AclScopeTree.
Markup only — every @onclick, binding, disabled and arm->confirm flow is
unchanged.
