When SIMULATE_PLC=true, a background task randomly disrupts rem or flt
signals on equipment (rem=false for 5-15s, flt=true for 3-10s) to
exercise fault detection, comm lock, and recovery logic in the engine.
Uses XorShift64 PRNG with no extra dependencies.

Remove the standalone GET /api/unit/runtimes endpoint in favour of
embedding runtime directly in existing responses:
- GET /api/unit → each item now includes `runtime` field
- GET /api/unit/:id → returns UnitWithRuntime
- GET /api/unit/:id/detail → UnitDetail now includes `runtime`
runtime is null when the engine has not yet initialised the unit.
Frontend loadUnits() reads the embedded runtime field to populate
state.runtimes — one request instead of two.

Root cause: state.runtimes was empty after refresh because the engine
only pushes UnitRuntimeChanged on state transitions — if the engine
is mid-wait-phase, no push occurs and badges show OFFLINE.
Fix: add GET /api/unit/runtimes batch endpoint (returns all known
runtimes as { unit_id: UnitRuntime }) and call it in parallel with
the unit list fetch inside loadUnits(), so runtime badges are correct
immediately after page load.

Backend:
- POST /api/control/unit/batch-start-auto — starts auto on all enabled
units that are not fault/comm locked and not already running auto
- POST /api/control/unit/batch-stop-auto — stops auto on all units
Frontend (ops view):
- Add "全部启动" / "全部停止" buttons in the unit sidebar header

Returns unit with its equipments, each embedding their bound points.
Uses 2 queries (equipment list + points via ANY) to avoid N+1.

Prevents browser from caching JS/CSS modules, so frontend changes take
effect immediately on page refresh without needing hard refresh.
