fix(driver-ablegacy): fix CS9124 build error and update stale status-mapper test

EffectiveCipPath now references ParsedAddress/Profile properties instead
of the captured primary-constructor parameters to avoid CS9124 (param
captured into enclosing type AND used to init a member).

NonZero_libplctag_status_maps_via_AbLegacyStatusMapper updated to pass
(int)Status.ErrorNotFound rather than the stale magic integer -14 that
the old mapper happened to handle but the new enum-based mapper does not.
