BIG FIX: profile save + sport classification + KUD separation

1) auth/auth_v2.py — update_me bug fix:
   PUT /auth/me return value was 'return me(user)' but me() is a
   FastAPI route handler, not callable directly. Replaced with explicit
   re-fetch returning correct JSON shape. Profile changes now persist
   in UI after save.

2) DB: HNK Goranin Delnice (id 782) sport='skijanje' → 'nogomet'
   + napomena cross-contamination cleaned (id 782, 192, 347, 2280)
   + general rule: NK/HNK/Nogometni klub → nogomet
   + RK/Rukometni klub → rukomet
   + OK/Odbojkaški klub → odbojka

3) DB: KUD/folklorne/lovačke/vatrogasne udruge marked as
   sport='kulturno-umjetnicko' + razina='NE-sportsko' so frontend
   can filter them out of sportski savezi list

4) Backup: pgz_sport.klubovi_backup_20260505_0857

Verified: PUT /auth/me with damir@pgz.hr persists telefon change to DB
and returns fresh data
