Global stats: rankings, daily token chart and time ranges

[skyfallwastaken]

Global stats was one totals row and a table of raw model ids. It now works like OpenRouter's rankings.

• Time range: 24 hours, 7 days (the default), 30 days, or all time, kept in the URL (/global?range=month).
• Headline numbers: requests, tokens and active users for the range.
• Tokens per day: a stacked bar chart over the last 30 days, split by the top 8 models plus "Other". Hovering a day shows a breakdown, and a legend is always shown. It uses the validated 8-hue categorical palette, with separate light and dark steps.
• Top models: a leaderboard ranked by tokens, showing the catalog name, the id, share of tokens and requests. Routing variants (:nitro, :floor) count towards their base model. Only listed models link to /models/…, so no more 404s.
• Top authors: share of tokens by model author (openai, google, moonshotai, …).

Each range is one set of ClickHouse aggregates, cached for 60 seconds like the old global stats. globalStats / modelStats are replaced by globalOverview(range).

Screenshots

The demo ClickHouse was seeded with 30 days of synthetic traffic from 140 fake accounts, so the charts have something to show.

Testing

• read-model.test.ts (real ClickHouse) checks:
  • per-range totals and active users;
  • variants folding into the base model;
  • the author fallback for non-OpenRouter ids;
  • chart series order;
  • 30 zero-filled UTC days.
• bun run typecheck, bun run check: 0 errors. bun test: 0 fail.
