Add usePermission() guards across Vue client pages and components:

- DeviceTable: Reboot button only when devices.control
- ActionScriptsGrid: Run button only when scripts.run
- ScriptTable: Enable/Disable only when scripts.edit
- AreaTreePage: Create area only when areas.manage
- AreaDetailPage: Rename/Assign/Unassign/Remove only when areas.manage
- DeviceDetailPage: Edit/Assign/Reset only when devices.edit; ReSetup only when devices.setup; Reboot only when devices.control; Remove only when devices.delete; Firmware Update only when firmware.upload
- DevicesScanningPage: Add (setup) button only when devices.setup
- ScriptDetailPage: Run only when scripts.run; Assign/Unassign/Enable toggle only when scripts.edit
- ScriptsScopesPage: Enable/Disable only when scripts.edit
- FirmwaresListPage: Refresh Catalog only when firmware.upload

Fix ActionScriptsGrid.spec.js to seed auth store with scripts.run permission.

All 167 tests pass.
