Fix contact methods JSON string/array duality in PlatformServiceMixin

- Add ContactMaybeWithJsonStrings type usage for internal database operations
- Implement $normalizeContacts() method to handle both JSON string and array formats
- Update $contacts(), $getContact(), and $getAllContacts() to use normalization
- Fix $updateContact() to properly convert contactMethods arrays to JSON strings
- Add validation to filter out malformed contact method objects
- Update ContactEditView to handle malformed data gracefully

Resolves issue where contactMethods could be stored as JSON strings in database
but expected as arrays in components, causing "Cannot create property 'label' on number '0'" errors.
