Redact tool: rich UI, multilingual, engine choice, output formats

- Custom inline form (EN/NO/UK/PL lang switcher) replacing generic stub
- Engine selector: Azure gpt-4o-mini (default), gpt-4o, GPU cuttlefish, regex-only
- Entity type toggles: names, organisations, places, dates of birth
- Output formats: contextual role tags, generic [PERSON], Norwegian pseudonyms
- Keep officials mode: judges/experts kept as [JUDGE: Andersen] format
- Exempt names list: specific names excluded from redaction
- Hint paragraphs explaining each option in all four languages
- Backend: engine routing, callGpuLlm(), applyGenericTags(), applyPseudonymization()
- AzureOpenAiGateway: withDeployment() clone pattern for per-call model override
