Replace the last two holdouts: the dashboard partner-identity fallback now uses the real useMe().partner name, and the decorative MRR sparkline (dashboard + reports) moves to a generated useMrrTrendline() — deterministic, clearly placeholder-only, until a daily MRR-snapshot job exists. Removes the dead sparkLast/sparkTrendPct vars. The data/customers.ts fixture module is now fully deleted; the partner portal carries no mock business data.
