feat(sub): redesign the subscription page around usage, tabs and app imports

The info page was a long key/value table followed by every link and two
app dropdowns, and it rendered left-to-right even for Persian and Arabic.
It now leads with a usage ring, the remaining quota and a stats grid, and
splits the rest into Subscription / Apps / Configs tabs.

- Status tells expired, data-used-up and disabled apart instead of one
  "Inactive", replacing the hard-coded English expiry chip.
- The Apps tab keeps every Android and iOS app with its existing deep
  link, preselects the visitor's platform and adds Windows: Hiddify and
  Clash Verge Rev import directly, v2rayN copies the link.
- fa-IR and ar-EG render right-to-left; URLs, IDs and sizes stay LTR.
- The footer shows the support link and the client refresh interval, so
  subPageContext now carries subUpdates (also in ?format=info).
- Status, days-left and app deep-link logic lives in subPageModel.ts,
  with unit tests pinning the deep links the page already shipped.
