Per-vertical earnings panel for the publisher rev-share dashboard.

publisher_id resolves to either the Publisher PK id OR the tenant_slug (the listener HEX-FLO referral mechanic surfaces the dashboard by slug; older callers may pass the id). Both work.

Returns the real shape with zeros when no plays exist — never random or fabricated data. Per-vertical breakdown joins plays -> articles for this publisher, plus a deterministic trending_share = publisher's vertical-listens / total-listens-in-vertical over the window. Estimated payout uses the placeholder formula $0.01 / listen until the ledger settlement engine lands; the same rate the HEX-FLO mechanic quotes externally.
