The ignored and ignoredPatterns allowlists lose their fields on load

[jzonthemtn]

Policy flattens ignored to a list of terms and ignoredPatterns to a list of pattern strings, so ignored[].name, ignored[].caseSensitive, ignored[].files, and ignoredPatterns[].name are dropped on load and lost on save.

Acceptance Criteria

• The allowlist objects round-trip whole.
• caseSensitive and files are honored when matching.
• spec/v1.0/examples/26-filter-options.json round-trips with no field lost.

Closes a gap against the PhiSQL specification. No RFC: $defs.ignored and $defs.ignoredPattern predate v1.0.
