Track and surface a subscription's enabled state from backend to frontend so the UI can show inactive subscriptions and use it in active-state logic.
Changes:
- sub/subService.go: track hasEnabledClient, set traffic.Enable, add Enabled to PageData and populate it in BuildPageData.
- sub/subController.go: include enabled in the page context.
- web/html/settings/panel/subscription/subpage.html: emit data-enabled attribute and render an "inactive" tag when disabled.
- web/assets/js/subscription.js: read data-enabled and include it in isActive() checks.
This ensures subscriptions with no enabled clients are marked inactive in the UI and excluded from being considered active.
