fix(advisory): treat int-keyed ignore entries as plain IDs

parseIgnoreWithApply distinguishes ['CVE-123' => 'reason'] from
[0 => 'CVE-123'] by checking is_int($key) in PHP. AuditConfig only
matched on the value's type, so a canonical-int-keyed string value
was mistaken for an id => reason pair. Expose canonical_int_key from
the php-shim to replicate PHP's key-canonicalization rule and
unignore test_mixed_formats.
