fix(capital): await onSaved before advancing wizard past БЛАГОРОСТ step

goNext() checked getFirstAvailableCouncilGroup() (which reads isDocParamsReady,
derived from onboardingState.capital_program_doc_data_hash) synchronously right
after saveParams() resolved. But saveParams() fired options.onSaved(hash) without
awaiting it, and the card's onSaved handler did `void handleDocParamsSaved()` —
an async refetch of onboarding state — so isDocParamsReady was still stale at the
moment goNext() decided which council group to jump to. getFirstAvailableCouncilGroup()
returned null, setWizardStepKey never ran, and the wizard just re-rendered the same
БЛАГОРОСТ step, looking like the just-saved params were never registered.

Fix: onSaved is now awaited inside saveParams(), and the card passes the
handleDocParamsSaved() promise through instead of firing it and forgetting it.
