The admin source-config settings form failed to load with "Failed to
fetch tender-radar source config". Network trace showed
GET /modules/tender-radar/source-config returning 404.
Root cause: NestJS RouterExplorer maps routes in method-declaration
order. `@Get(':id')` was declared before `@Get('source-config')`, so
the param route captured "source-config" as an id and shadowed the
static handler (401 unauthenticated, 404 past the guard — no Tender
with id "source-config").
Fix: declare `@Get('source-config')` before `@Get(':id')`. Add a
declaration-order regression test — unit tests call controller methods
directly, bypass routing, and could never catch route shadowing.
Verified live: settings form now loads real config, interval save
persists and live-re-registers the scheduler (INGEST-06). Phase 10
verification raised human_needed -> passed after full browser UAT.
