- Extract AssemblePayments(ctx) from ServePayments in api/handler.go,
mirroring the AssembleAdults/AssembleJuniors pattern
- Add PaymentsPageData view-model wrapper in render.go
- Rewire html_handler.go ServePayments to call AssemblePayments and
render with PaymentsPageData
- Replace payments.tmpl placeholder with real grouped-by-person ledger:
alphabetical member blocks, txn-table (Date/Amount/Purpose/Message),
newest-first rows, Unmatched/Unknown bucket
- Append ledger CSS classes to app.css (.ledger-container, .member-block,
.txn-table, .txn-date/amount/purpose/message, tr:hover)
- Add TestPaymentsPage markup test
