Jack 96a416629d refactor: change GetFlattedMetaByKBs return type to common.MetaData (#15656) ...

## Summary

Change `GetFlattedMetaByKBs` return type from `map[string]interface{}`
to strongly-typed `common.MetaData`.

**Depends on**: #15648 (provides `MetaData`, `MetaValueDocs` types)

### Changes
- `service/metadata.go`: Changed return type, removed type assertions
- `service/metadata_filter.go`: Updated all metadata function signatures
- `service/metadata_filter_test.go` (new): 12 test cases

### Bug fix
`applySingleCondition` used `.([]interface{})` assertions on `[]string`
data, silently breaking operators like `!=`, `contains`, `start with`,
etc.
