Tier engine strings (claude_haiku/claude_sonnet) were stripped back to
azure_mini by per-method whitelists, so both tiers ran gpt-4o-mini and Pro
charged 2x for the same model. Add a shared DbnBedrockModelRouter::
deploymentForEngine() helper and route the cloud path through it across
summarize, ask, barnevernet, discrepancy, deep-research, and korrespond.

Routes AI tools across three tiers based on task complexity:
- Azure GPT-4o-mini always: redact, translate, timeline-basic, search-legal (mechanical tasks)
- Claude Haiku 4.5 (Bedrock): ask, summarize, timeline-deep, citations (Norwegian nuance)
- Claude Sonnet 4.6 (Bedrock): korrespond, legal-analysis, deep-research, barnevernet-analyze,
discrepancy-find, advocate (public-facing legal output)
No AWS credentials in app — credentials live in LiteLLM on Colin (same as nova-lite).
Rollback: DBN_BEDROCK_ENABLED=false in .env, no code push needed.
Includes extended thinking support for Pro deep-research via chatWithThinking().
Claude Opus 4.7 constant added for future premium tier (needs litellm_config.yaml entry).
