Why

Operator's typed model configuration does not preserve model_version, preventing explicit selection of Temporal Envelope v2. Its seasonality validation also rejects the new calendar_month option.

Changes

Preserve omitted, v1 and v2 selections for univariate and multivariate Envelope models. Validate version-specific monthly seasonalities and the multivariate dependency_strength output, and document the v1.32.0 image requirement and fresh-fit requirement when switching versions.

No CRD changes are needed: these fields belong to the existing model configuration. Server TLS/mTLS support remains separate in #2794. The default image version is unchanged; select v1.32.0 or newer explicitly.

Validation

• Round-trip tests cover both class aliases and full paths, omitted versions, explicit v1/v2, and new seasonalities.
• Negative tests cover unsupported/empty versions, incompatible seasonalities, duplicates and the v2-only multivariate output.
• go test ./internal/controller/operator/factory/vmanomaly/config ./internal/controller/operator/factory/vmanomaly passed.
• go vet ./internal/controller/operator/factory/vmanomaly/... and git diff --check passed.
