listTenders now delegates where/orderBy composition to
tender-query.builder.ts (buildTenderWhere/buildOrderBy) instead of the
fixed status/publishedAt clause; pagination bounds unchanged (T-10-15).
New GET /modules/tender-radar/coverage handler returns active-tender
counts grouped by sourcePortal (D-12, UI-05 coverage banner data
source). Declared before @Get(':id') — same static-route-before-:id
convention as source-config (Pitfall 5, Phase-10 regression guard).
Extends tenders.controller.spec.ts: sort whitelist pass-through,
unknown-sort fallback, pagination skip/take, coverage response shape,
and a declaration-order regression test for getCoverage.
