Let n8n create and update campaigns with scope sources

Replace the separate Add Source operation with multi-select source
fields on create and update. Create passes accessReviewSourceIds to
the existing GraphQL input; update gains the same omittable field and
backend source sync so workflows can configure sources in one step.

Load source options from the organization in the n8n UI, and keep
surfacing INVALID errors when start fails for missing sources.
