1) HNS direct link u research_links: za sportaš s profile_url/source_url
(npr. https://semafor.hns.family/igraci/X/...) generira [⭐DIRECT] link na vrhu liste,
umjesto generic Google search. _research_links sada prima row dict.
2) Avatar cache buster: applyMeToHeader dodaje ?t=Date.now() na sve avatar img tagove.
Avatar upload handler dodatno persistira novi avatar_url u localStorage.pgz_user
tako da preživi page refresh + cross-page navigacije.
3) Logo home link: <div class='logo'> → <a href='/' class='logo'> u app.html i sport2.html.
Klik na PGŽ SPORT logo vodi na public portal.
4) Klub → Sportaši drill-down: u klub Info tabu dodan button
'👥 Vidi sportaše ovog kluba (N)' koji prebacuje na k-clan tab.
Plus '🌐 Službena stranica' link kad klub ima web.
5) Smarter klub enrichment:
- URL validacija (skip placeholder strings poput 'godisnjak_zspgz_2025')
- Domain candidate guesser (slug → 16 candidate URLs s common HR TLD-ovima i sport prefix-ima)
- Parallel HEAD probe (8 threads, 10s budget) — first 200 + name token match wins
- Subpage scrape (/kontakt, /uprava, /o-nama, /o-klubu, /predsjednik) za richer evidence
- HNK Orijent (id 3766) test: pogađa https://www.orijent.hr/, predlaže web+email+telefon+opis
E2E verified:
- 9/9 sidebar URL-ova → 200
- /users/me/gdpr-export → 200 (28KB JSON)
- /users/me/request-deletion → 200 (DB row pgz_sport.gdpr_erasure_requests)
- /enrich/klub/3766 → 4 proposed fields (web, email, telefon, opis)
- HNS sportaš research_links: ⭐ HNS profil DIRECT link na vrhu
