refactor: improve relay hint selection and relay management

Browse Source 
- Extract updateKeepAlive and updateAddressLoader helpers in App.tsx for better code reuse
- Improve relay hint selection in HighlightItem with priority: published > seen > configured relays
- Add URL normalization for consistent relay comparison across services
- Unify relay set approach in articleService (hints + configured relays together)
- Improve relay deduplication in relayListService using normalized URLs
- Move normalizeRelayUrl to helpers.ts for shared use
- Update isContentRelay to use normalized URLs for comparison
- Use getFallbackContentRelays for HARDCODED_RELAYS in relayManager
