Replace all bare useAuthStore(), useBlockingStore(), and
useSuccessNotification() calls with individual field selectors.
This prevents components from re-rendering when unrelated store
fields change.
- 21 useAuthStore usages across 20 files: individual selectors
for 1-2 fields, useShallow for 3+ fields
- 5 useBlockingStore usages: individual selectors
- 2 useSuccessNotification usages: individual selectors
- 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)
