agent-platform release v4.120.0

Changed

• The serving preset catalog is published wherever the connectivity chart runs, model serving off included (giantswarm/agent-platform#847). The ServingPreset ConfigMaps (agent-platform.giantswarm.io/serving-preset=true, with the agent-platform.giantswarm.io/chart-version annotation) render in the release namespace whether or not components.modelServing.enabled is set, from the same catalog (files/model-serving/presets/*.yaml plus modelServing.presets, shippedPresets.enabled / .exclude honoured), so model-manager’s check_fit answers a preset’s declaration before a GPU pool and its backend exist. The chat-template ConfigMaps, the discovery ConfigMap and every serving workload stay behind the switch; with it on the render is unchanged. make verify-preset-catalog asserts both sides.
