fix: resolve multiple miniprogram bugs and extend admin console

- fix manual bind stuck at BLE scan, redirect to bind-success
- add 15s timeout and stopScan to ble-connect
- add stopScan method to ble.js
- add back-to-home button on bind-success page
- fix field name in subscribe-plans (plan -> plan_type)
- fix history.js to handle created_at field
- fix index.js to handle device name field
- add subscription route alias in request.js
- extend admin cloud function from 1 to 9 actions
- add mock mode to admin-console request.js
- remove unused discover page and legacy record function
