The webhook compiles `ForbiddenLabels.Regex` for both labels and annotations, so a malformed annotations regex can be persisted. Once stored, namespace admission later evaluates the bad regex through `pkg/api/forbidden_list.go`, where `regexp.MustCompile` can panic and cause admission failure.\n\n### Details\nIn `internal/webhook/tenant/validation/forbidden_annotations_regex.go`, `OnUpdate` validates the new Tenant object, but the loop compiles `tnt.Spec.NamespaceOptions.ForbiddenLabels.Regex` for both `labels` and `annotations`. That means an invalid `ForbiddenAnnotations.Regex` is never validated if `ForbiddenLabels.Regex` is valid.\n\nRelevant paths:\n- `internal/webhook/tenant/validation/forbidden_annotations_regex.go`\n- `internal/webhook/namespace/validation/user_metadata.go`\n- `pkg/api/forbidden_list.go`\n\nNamespace admission later calls `api.ValidateForbidden(...)`, and `ForbiddenListSpec.RegexMatch()` uses `regexp.MustCompile(in.Regex)`.
