R7+: 5x P0 demo fixes — HNS direct link, avatar cache, logo home, klub→sportaši, smarter enrichment

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
