feat: Faza A2 -- cautare companii, segmente salvate, research briefs

- pagina Companii: cautare Apollo prin ceo-api, salveaza cautarea ca
  segment, creeaza research brief per rezultat
- pagina Segmente: reruleaza o cautare salvata, sterge
- pagina Research: listeaza briefs cu surse (linkuri catre Apollo/altele)
- Overview devine un briefing determinist (restante/urmatoarele 7 zile
  + activitate saptamanala), cu explicatia AI marcata explicit ca
  neconstruita in loc de ascunsa
