Horoskop in kozmicni dogodki: dnevno AI generiranje + scheduler

- Nov dnevni scheduler (server/scheduler.ts): vsak dan ob zagonu in vsakih 6h
  preveri/generira horoskope in kozmicne dogodke (prej samo enkrat ob zagonu)
- Kozmicni dogodki so zdaj AI-generirani in dnevni (nova tabela cosmic_events
  + /api/cosmic-events), namesto hardcoded fiksnih datumov iz feb/mar 2026
- Naslovni horoskop widget bere pravi AI horoskop za danes (prej staticni tekst)
- Frontend: staleTime 30min + refetchOnWindowFocus za dnevno osvezevanje
