Per-dialog context-composition breakdown for the InfoCard 10×10 grid.

Returns the categorised input/output token split for one LLM dialog. Built asynchronously by a process.nextTick dispatch from routes/logic/sendResponse.js after res.json has flushed, so the breakdown is typically available within ~50 ms of the dialog completing — but the InfoCard MUST handle the “pending” race window by retrying on 404 — composition pending.

Input categories (12 total) roll up into 3 ownership boundaries:

system: persona, systemRules, toolDefinitions, toolInstructions, toolGuidance, formatting
twin: digitalTwin, assistant, rag
user: userContext, history, toolResults

Output categories (3 total): thinking, completion, toolCalls.

Permission: caller must own the dialog (History.user === req.user._id), OR be accountType === 'super'. Dialogs flipped to forgotten:true return 404 (same behaviour as the rest of /api/user/history/:id/*).
