Merge the two "by Model" pies (Token Usage + API Requests) into one
dual-pie card with a shared right-side vertical legend and per-donut
center totals, drop the standalone API-Key Top 10 chart, and put the
combined chart side-by-side with the User Top 10 ranking in one row
with the same 16/8 column ratio used by the System Load section above.
* New component usage-charts/usage-by-model.tsx owns both metric queries
(group_by=['date','route']), aggregates a shared route→color map so
the legend toggles both donuts together, and renders two pies at
centers ('20%','50%') and ('60%','50%') with radius ['50%','70%'].
* new-usage.tsx no longer mounts ApiRequestsByModel / TokenUsageByModel
/ TopTokenUsageByApiKey; layout collapses to two columns sized
(lg=24 xl=16) and (lg=24 xl=8).
* Delete unused token-usage-by-model.tsx, api-requests-by-model.tsx,
top-token-usage-by-api-key.tsx, and the use-top-token-usage-by-api-key
hook.
* Strip the now-unreferenced dashboard.tokenUsageByModel /
apiRequestsByModel / topTokenUsageByApiKey locale keys across 5
locales, add the new dashboard.usageByModel title; locale parity
check passes.
Align dashboard with the route dimension introduced in the previous
commit:
* Token Usage / API Requests pie charts query the breakdown API with
`group_by: ['date', 'route']` and aggregate via the new `route`
dimension in `buildUsageLabel`. Visible chart titles keep the existing
"by Model" wording — only the underlying data dim changed.
* Overview "Models" card label switched to `dashboard.deployments`
("部署" / "Deployments"), and the Active Models table heading to
`dashboard.activeDeployments`. These reflect the underlying entity
(model deployments) more accurately now that routes are the
user-facing model concept.
* Drop 11 unused dashboard locale keys (`dashboard.title`,
`dashboard.models`, `dashboard.allocategpus`, `dashboard.instances`,
`dashboard.disk`, `dashboard.diskutilization`, `dashboard.apirequest`,
`dashboard.activeModels`, `dashboard.activeUsers`,
`dashboard.activeModels.name`, `dashboard.runninginstances`) — no
remaining references in `src/` after the rename. Locale parity check
passes.
