Add a ledger read endpoint GET /v1/overview returning recent ledger activity and the real 24h hourly transaction count, seed demo transactions through a Liquibase demo changeset, and wire the web overview to live data. Drop the fabricated mock, the version/build/uptime line and the fake service-health chips; offline and empty states show placeholders instead of invented numbers.

What
Replaces the fabricated Overview mock with live ledger data.
GET /v1/overview(scopeledger:read) returning recent ledger activity (transactions + accounts, 1:1 row->event, no double counting) and the real 24h hourly transaction count. Thin controller ->OverviewService(@Transactional(readOnly = true)) -> hand-written mapper. Native projections are parameterized; sparkline buckets are UTC-anchored.demo/002-demo-transactions.sqlseeds 10 balanced USD transactions + entries + derived balances via ademo-context Liquibase changeset. Both entry legs land in one changeset so the deferred double-entry trigger passes at commit; timestamps areNOW()-relative so the 24h sparkline populates on a fresh sandbox.useLedgerOverviewfeeds the activity list and the transactions sparkline; user/tenant come from JWT claims (display only). The fabricated version/build/uptime line and fake service-health chips are dropped (a static SPA cannot honestly assert them). Offline and empty states show placeholders, never invented numbers.Verification
