EstadoAlarmas, EstadoGrabacion and EstadoRadio defaulted `esPremium` to
`() => true`, so any construction site that forgot to wire entitlement
compiled fine and silently ran ungated — failing OPEN to premium and
disabling the paywall with no test able to catch it.
The parameter is now required with no default. Production wiring in
app.dart was already correct and is unchanged; the 184 pre-existing test
call sites now pass `() => true` explicitly, which is exactly the old
implicit default, so every assertion is untouched.
EstadoRadio has no gate of its own but constructs EstadoGrabacion, so it
inherits the same contract.
The one test that existed to pin the old default is renamed to describe
what it still covers (the premium path through iniciar() with no
duracion); its assertions are unchanged.
Wires EstadoAlarmas.ultimaExcepcionPara into PantallaAlarmas: an
alarm with an outstanding scheduling-failure exception now shows a
calm warning line (distinguishing a pre-notice-only failure from the
alarm itself not being registered) with a tap target into the
reliability diagnostics screen. The warning is its own small tap
target nested inside the existing card InkWell, so tap-to-edit,
swipe-to-delete and the hero "Saltar" chip are untouched.
Adds alarmCardSchedulingFailedMessage/alarmCardPreNoticeFailedMessage
to all 13 ARB locales with real per-language translations (verified
against arb_parity_test and arb_anti_copy_test).
