AI-admin: alias-rename, dollarkostnad, fikset kolonnebredder

- PATCH /aliases/:id støtter nå rename (alias-felt)
- Alias-raden har «Rediger»-knapp → inline-redigering av navn + beskrivelse
- Tokenforbruk viser model_actual og estimert dollarkostnad per rad
- Dollarkostnad beregnes fra OpenRouter-katalogpriser (krever lastet katalog)
- Tokenforbruk-tabellen bruker auto-kolonnebredde (fikser overflow)
- «Kompl.» i stedet for «Completion» i header
