feat(adminui): S7 typed driver page

Adds S7DriverPage.razor (route: /clusters/{id}/drivers/new/s7) with
typed fields for host, port, CpuType InputSelect, rack, slot, timeout,
probe sub-options, and read-only JSON tag view. FormModel uses flat
settable properties and FromOptions/ToOptions round-trip; no
init-only bindings in Razor. Also adds
S7DriverPageFormSerializationTests (3 tests: JSON round-trip,
unknown-field drop, FormModel round-trip).
