Oracle: pin the hooks ignore-value inert-entry refusal

Three hadmin-ignore-value-inert-* cases record the engine's port of
be87f5eb (#662) to hooks ignore-value: an exact value for a rule whose
findings can never extract one is refused with the wildcard-plus-file
route (and no config write), while the wildcard scoped form for the same
rule is accepted. Goldens recorded from the engine binary and verified
byte-for-byte against the ea360025 hook-admin.mjs on the same sequences.
No existing golden changes, so no DELTAS entry is owed.

Prepared with AI assistance (Claude Code).
