CC1 R3B-Mreža M1+M2+M3 — autocomplete + 3D centar + forensic enrich

M1 (default centar):
- Augment /api/v1/presenter/graph-real with synthetic 'pgz-savez-nogometni' anchor
  (PGŽ gold, size 40), connected to top 3 person + top 3 entity nodes
- centerMrezaOnAnchor() called 1.5s after render and via "🎯 Centar (PGŽ)" button

M2 (autocomplete):
- Backend GET /api/v2/search/suggest?q=&type=person|club|company
  Searches pgz_sport.klubovi, pgz_sport.savezi, pgz_sport.clanovi,
  civic.persons, civic.entities; returns 20 results max
- Frontend: 3 inputs get keydown+input handlers, dropdown UI under each
  Enter → first suggestion, click → suggestion, blur → close
- centerMrezaOnSuggestion: finds existing node by label, or injects new node
  + edge from anchor and re-renders

M3 (forensic enrich):
- Backend POST /api/v2/forensic/findings/{id}/enrich
  Extract person name from entities_involved or title regex,
  hit hr.wikipedia.org REST summary, persist into raw_data.enrichment
- Frontend: forensicEnrichBlock + customFindingEnrichBlock added to alert
  panel and custom-finding panel (Liverić). Custom uses direct Wikipedia
  fetch since they're not in DB.
