Mirrors campaign.ts localStorage pattern to capture ?ref= from URL and pass
referral_code to backend during Telegram Widget, OAuth, email login, and
Mini App authentication. Fixes redirect loop when email auth is disabled.
- Add campaign.ts utility (capture from URL, localStorage with TTL, validation)
- Pass campaign_slug in all auth API methods (telegram, widget, email, oauth)
- Consume slug in auth store login methods, set pendingCampaignBonus state
- Add CampaignBonusNotifier component (toast on bonus, mounted in AppShell)
- Show web_link alongside bot deep_link in AdminCampaignStats
- Add CampaignBonusInfo type with union bonus_type
- Fix VerifyEmail: ref guard against StrictMode double-fire, setTimeout cleanup
- Fix AdminCampaignStats: setTimeout refs with cleanup, i18n-aware locale
- Wrap all localStorage access in try/catch (Safari private browsing safety)
- Add campaignBonus translations (ru/en/fa/zh)
Skip code-based flow for unverified emails — replace email directly
and send verification to the new address. Show success step immediately
instead of asking for a verification code.
- Validate authorize_url is HTTPS before redirect (open redirect prevention)
- encodeURIComponent on provider name in API URL paths (path traversal prevention)
- encodeURIComponent on referralCode in t.me deep link
- Gate console.warn behind import.meta.env.DEV (no info leak in prod)
- Add OAuthProvider type and extend User.auth_type union
- Add OAuth API methods (providers, authorize, callback)
- Add loginWithOAuth to auth store
- Create OAuthCallback page with state validation
- Create OAuthProviderIcon component with brand SVGs
- Add OAuth buttons to Login page between Telegram and Email
- Add OAuth callback route to App.tsx
- Add translations for ru, en, zh, fa
