feat(form-builder): add PublishGuard framework + 9 concrete guards (WS-6)

Per-purpose schema validation composes a PurposeGuardProvider returning a list of guards. Errors collected (not first-fail) so the builder UI surfaces every issue per save. ConditionalRequirement composes higher- order without proliferating one-off classes. RequiresIdentityKeyBinding checks the is_identity_key flag specifically; the binding-existence check is handled additively by the existing assertRequiredBindingsPresent in FormSchemaService. SchemaHasLinkedEvent checks owner_type='event' + owner_id (FormSchema uses polymorphic owner; there is no direct event_id column). i18n messages live in lang/nl/form_builder_publish_guards.php.
