Ran knip to find unused exports/dependencies (deps already clean, no
unused packages/files found).
Removed genuinely dead code (verified zero references anywhere,
including templates):
- 4 unused constants in config/constants.ts (scroll/pagination/search
thresholds never consumed)
- isAdminRole(), toSearchResult(), createInitialSearchState(),
getTranslatedCategoryName() - unused utility functions
- DEFAULT_EDITOR_HEADER_CONFIG - unused constant
- TelegramService - entire file deleted; cart.component.ts/
cart.service.ts already implement the same window.Telegram.WebApp
access directly, this was an unused duplicate
Real bug fix found during the sweep: SeoService has providedIn:'root'
with a live effect() meant to sync <title>/OG/canonical tags to
tenant bootstrap config, but nothing in the app ever injected it, so
Angular never instantiated it and the effect never ran - the SEO sync
a prior sprint reported as "done and verified" was actually dead on
arrival. Fixed by injecting SeoService in the root App component.
Left alone: ~125 knip-flagged "unused exported types" - overwhelmingly
config/schema interfaces for the widget/theme/admin domain models,
high false-positive rate for this kind of interface-heavy Angular app,
deleting blind risks breaking structural type contracts. Also left
locally-used-but-over-exported helpers (toCssColor/toBackendColor,
HTML_EDITOR_TOOLBAR*, HISTORY_LIMIT, DEFAULT_CATALOG_PAGE_SIZE) - real
code, not dead, just exported wider than needed.
tsc --noEmit and ng build --configuration=production both clean (only
pre-existing bundle-budget warning, unrelated).

- CartPaymentRequest gains qrDescription (brandName > hostname > fallback
text) and customerID (telegram id)
- QrCreateResponse gains qrTTL; polling window now derived from it
(min 60s) instead of a fixed 3-minute/36-check cap
- PAYMENT_MAX_CHECKS replaced by PAYMENT_MIN_POLL_SECONDS
