feat(dashboard): daily cost line + This Month timezone fix#151
Merged
Conversation
Adds a per-day cost line (accent color, right y2 axis) on top of the existing stacked bar chart. Cost is accumulated per model during the daily aggregation pass so per-model pricing is applied correctly, then rendered as a Chart.js line dataset with a dedicated y-axis.
…UTC shift toISOString() outputs UTC, so in UTC+ timezones midnight local time converts to the previous UTC date — causing "This Month" to include the last day of the previous month. Use getFullYear/getMonth/getDate (local) instead.

PR #151 fixed getRangeBounds to format range bounds from local date components, but rangeIncludesToday still derived 'today' via UTC toISOString(), so the two could disagree near UTC midnight. Extract a shared localISODate() helper and use it in both, removing the duplicated formatting expression. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Thanks @paulabenzar — merged and shipped in v1.5.5. Both changes are in: the per-model-priced Est. Cost overlay on the Daily Token Usage chart (priced before the daily aggregation, so multi-model days are correct) and the This Month UTC+ timezone fix. Follow-up on top of your commits: I applied the same local-date fix to Written by Pawel's agent |

Summary
linedataset on a dedicated right-side y-axis (accent color), computed per model before the daily aggregation so per-model pricing is applied correctly. Toggleable via the legend like all other series.getRangeBoundswas usingtoISOString()(UTC) to format dates constructed from local midnight, which shifted one day back. Now usesgetFullYear/getMonth/getDate(local) throughout.Test plan
