tsx runs tests without type checking and tsconfig.json covers only src,
so 71 type errors had accumulated unnoticed. tsconfig.tests.json now
checks every test and helper, and npm run typecheck includes it.
Fixtures gain the fields the DTOs have grown since they were written
(manualQuantity, circuit apparent power/cos phi, downstream board loads,
section totals, building, cover and board info fields). Repository
lookups that return "row ?? null" now declare the null in their type,
which their callers already handle.

Every assert.throws now names the error it expects, so a broken fixture
or an unrelated failure can no longer satisfy a rejection test. Zod
rejections are matched by issue path and code via tests/support/zod-assertions.ts.
Restore snapshot coverage lost with the release baseline: invalid board
floor, room floor and circuit section references and a reserve state
that contradicts the device rows are rejected again under test.
