fix: resolve quality audit issues

- utils.js: force UTC+8 output to match MySQL timezone on SCF
- admin subscriptions: return stats (plan counts + revenue) in response
- admin devices: implement keyword search filter
- device-detail: fix binding history field names (bind_time/unbind_time/bind_status)
- user-detail: fix treatment time field (start_time not started_at)
- dashboard: show actual mode per treatment, use sub_stats from dashboard API
