fix(awards): "no field" leaves no rule running behind the panel

Choosing "no field" cleared the primary field and hid the matching controls —
but the fallback OR rules stayed in the definition and went on scanning their
own fields. An RDA award declared to match nothing still found a district in the
QTH, and the panel no longer showed the rule doing it. Only a manual override on
the same QSO kept the wrong reference out of the log.

So the choice now clears the fallbacks too, which is what its label promises,
and a rule that survives — from an imported definition, a shared template — is
rendered even in "no field" mode. Nothing that still runs may be invisible.

No catalogue award pairs an empty field with OR rules, so nothing shipped
changes behaviour.
