📝 Full Task Prompt

Update `dashboard/src/v2/lib/agent-preset-api.ts` so the serialized payload for both `createAgentPreset` and `updateAgentPreset` includes `containerRunAsRoot`. Add or extend dashboard API coverage in `dashboard/src/v2/lib/__tests__/agent-preset-api.test.ts` (or the existing agent preset editor save test) to assert that a root-mode change from `AgentPresetEditorPanel` survives the API boundary and is sent to the backend.
