test: tighten inspector workflow refresh assertions

CodeRabbit pointed out that the regression test carried an unused checklistPath and only asserted that empty workflow initialization produced some data. The test now keeps the setup focused and checks the exact default workflow count.

Constraint: Address actionable CodeRabbit feedback on PR #225

Confidence: high

Scope-risk: narrow

Tested: env -u GOROOT go test ./internal/app -run TestInspectorEnsureWorkflows -count=1

Tested: env -u GOROOT make test

Tested: env -u GOROOT make build

Tested: env -u GOROOT go vet ./...

Tested: git diff --check
