test(heartbeat): clean up workspace_operations + execution_workspaces before deleting companies

The PAPA-432 finalize fix writes workspace_operations rows during normal
heartbeat execution. Both heartbeat-process-recovery and
heartbeat-dependency-scheduling reuse a shared DB across tests and delete
companies between cases, but neither cleared workspace_operations or
execution_workspaces — the company_id FK then blocked teardown.

Add both tables to the cleanup ordering (before companies). All other
heartbeat suites either use tempDb.cleanup() or already clear these
tables.

Verified locally:
  pnpm exec vitest run \
    src/__tests__/heartbeat-process-recovery.test.ts \
    src/__tests__/heartbeat-dependency-scheduling.test.ts
  → 49/49 pass
