Port the dobetterlegal-tools two-tier quality stack to dobetternorge.no: QUALITY_TIERS registry + resolveTier (ToolModels), dbnToolsResolveToolRun (bootstrap), tier read+charge in the 6 analytical endpoints, Quick/Pro UI + payload.tier on the 6 tool pages/JS, and the bounded corpusContextForSummarize RAG fix (per-passage trim + total budget + reranker_enabled). Back-compat: requests without `tier` keep legacy engine behavior. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
