Rebuild /admin/subscription to pixel-match clinic-pro-tauri's
setting/purchase-subscription while keeping the real subscription/payment API:
- New PurchaseSubscriptionSidebar (orange-accent settings sidebar, routes preserved)
- New subscriptionIcons (SVGs copied verbatim from tauri source)
- Rewrite SubscriptionPage: 522px plan cards (gradient blur, popular badge,
secretaries pill, period toggle, dashed trial box), 365x104 current-plan card;
wired to /subscription/plans, /subscription/my, /subscription/trial and the
existing payment-gateway modal (no backend change)
- Expand tests: healthy/expiring/expired/no-sub, empty-plans, period toggle, buy modal
