fix: resolve list_matching_results deserialization error

- Add custom deserializer for MatchingResultStatus to handle empty strings
- Add serde(default) attributes to TemplateMatchingResultQueryOptions fields
- Update frontend to send undefined instead of empty string for status filter
- Fix 'unknown variant' and 'missing field' errors in template matching results

Resolves issue where selecting 'All Status' filter caused command failures.
