Add admin "My Positions — Income" panel

Aggregates every on-chain payment received by a set of owned IDs
(defaults to 21,24,25, saved to config.ownerIds and prefilled/auto-loaded
next time). Shows grand total + per-position totals and a merged,
newest-first ledger (to / from / entry-or-upgrade level / amount) via a
focused chain.getIncome read and an admin-gated /api/admin/income
endpoint. Verified: 5,064.43 POL across 21/24/25, 11 payments.
