feat(adminui): TwinCat typed driver page
Adds TwinCATDriverPage.razor (route: /clusters/{id}/drivers/new/twincat)
with typed fields for timeout, UseNativeNotifications, EnableControllerBrowse,
NotificationMaxDelayMs, probe sub-options (enabled/interval/timeout/admin
timeout), and read-only JSON views for Devices and Tags collections.
FormModel uses flat settable properties + FromOptions/ToOptions. Also adds
TwinCATDriverPageFormSerializationTests (3 tests). Fixes pre-existing
placeholder syntax error in AbCipDriverPage.razor (@raw_cpu_type in
attribute caused RZ9986).
