Before this change, every claim — matched or not — came back from
`/api/claims` with `receivedAmount: 0.0`. `to_ui_claim_from_orm`
hardcoded the value, so the Dashboard's 'Received' KPI and the
claim detail drawer's paid amount always read $0 regardless of
whether the claim had been paired with a paying remittance.
The fix threads the real value through the read path:
- `to_ui_claim_from_orm` accepts a new `received_total: float`
kwarg (default 0.0 for callers that don't have a remittance in
scope).
- `iter_claims` bulk-loads `Remittance.total_paid` for every
matched claim id in the result set (single SQL roundtrip via
`IN` filter — no N+1) and stamps the sum onto each claim dict.
- `manual_match` passes `float(remit.total_paid)` from the remit
it's already holding.
- `manual_unmatch` reads `paired_remit.total_paid` before clearing
the FK so the response still reports what was paid pre-unpair.
- `add` (write path) and `list_unmatched` (filters matched-remit
is NULL) pass `0.0` explicitly for readability.
The dev seed CLI now also generates matched Remittance rows for
every PAID/PARTIAL claim — `matched_remittance_id` is set on the
claim, and the remittance's `total_paid` is derived from the
billed amount using the same ratios the frontend's old sample
fixtures used (60–100% for PAID, 20–50% for PARTIAL). That gives
the Dashboard a non-zero 'Received' KPI on a fresh dev DB.
New tests:
- tests/test_iter_claims_received.py — 4 cases covering matched,
unmatched, orphan FK, and bulk-load paths. Catches regressions
if anyone re-introduces the hardcoded 0.0 or breaks the bulk
query.
