The bot backend now rejects prorated tariff switches from a free (0RUB)
tariff with 400 free_tariff_cannot_switch + use_purchase_flow=true
(TARIFF_SWITCH_RESET_FREE_DAYS: the free remainder must reset, not be
prorated over hundreds of accumulated days and carried to a paid
tariff). Handle it like the existing trial_cannot_switch contract:
- SwitchTariffSheet: accept free_tariff_cannot_switch in
shouldUsePurchaseFlow so the sheet hands off to the purchase form
- TariffPickerGrid: new subscription_on_free_tariff purchase-options
flag disables the switch CTA up front and shows purchase instead

Full scan of every page/component for the Connected-Accounts overflow class
(long user data with no truncation pushing siblings off the card on mobile),
adversarially verified. Applied min-w-0 + truncate (break-all for copyable
values, break-words for titles) on text columns and shrink-0 on fixed
siblings across ~23 files: AppHeader, dashboard/SubscriptionCardActive,
subscription purchase/sheets (TariffPurchaseForm, ClassicPurchaseWizard,
SwitchTariffSheet), SuccessNotificationModal, PurchaseSuccess, Wheel sub
picker, ReferralNetwork UserDetailPanel, and the admin pages (AnalyticsTab,
BrandingTab, SubscriptionSubRow, user-detail Info/Referrals tabs,
ApplicationReview, PartnerCampaignAssign, Partners, PromocodeStats,
PromoOfferSend, RemnawaveSquadDetail, TariffCreate, Tickets, Withdrawals).
The switch sheet's fallback checked detail.error_code, but the backend
sends detail.code — so the expired-fallback was effectively dead. Centralize
it into shouldUsePurchaseFlow(), which accepts either key and now also
handles the new trial_cannot_switch code: a trial has no paid value to
prorate, so the backend rejects the switch and the sheet hands the tariff to
the regular purchase form instead of surfacing a raw error.
The switch button is already hidden for trials via canSwitch; this is the
server-side backstop for races / direct calls, and it un-breaks the expired
fallback at the same time.
Move the tariff-switch preview modal (137 lines of inline JSX
+ its previewTariffSwitch query + switchTariff mutation + the
auto-scroll-into-view useEffect + the ref) into a self-contained
sheet at src/components/subscription/sheets/SwitchTariffSheet.tsx.
Parent keeps the trigger (switchTariffId selection state lives on
the TariffPickerGrid card click) but no longer holds the query, the
mutation, the ref, or the side-effect. The subscription_expired
backend signal — which used to call three setters at parent level
(setSelectedTariff, setSelectedTariffPeriod, setShowTariffPurchase)
— now flows through a single onExpiredFallback(tariff) callback.
SubscriptionPurchase.tsx: 2010 → 1841 lines (-169).
