- SubscriptionListCard: show traffic progress bar for limited subs
in multi-tariff list (was hidden because isActive excluded limited)
- SubscriptionListCard: amber border/background for limited status
cards (was using default neutral style, inconsistent with rest of UI)
- Subscription page: hide delete button for limited subs in
multi-tariff mode (limited subs still have valid days remaining)
- SubscriptionPurchase: allow tariff switch for limited subs
(was blocked by is_active-only gate in canSwitch formula)
- AdminUserDetail: include limited status in "already purchased"
tariff filter to prevent duplicate subscription creation
