td-sync Admin API Integration Tests

Write integration tests in internal/api/admin_integration_test.go using the harness in internal/api/testharness_test.go. Tests run against a real HTTP server on a random port with isolated temp databases.

Quick Start Pattern

func TestIntegration_DescriptiveName(t *testing.T) {
    t.Parallel()
    h := newTestHarness(t)
    state := h.Build().
        WithUser("user@test.com").
        WithAdmin("admin@test.com", "admin:read:server,sync").
        WithProject("proj1", "user@test.com").
        WithEvents("proj1", "user@test.com", 5).
        Done()

    token := state.AdminToken("admin@test.com")
    pid := state.ProjectID("proj1")
