Add stacked daily bars and a 7-day window to Total Spend

[mstallone]

TL;DR

The Total Spend card can now switch between the existing pie and stacked daily bars, and Yesterday is replaced with a 7-day window. Per-provider Yesterday tiles are unchanged.

What was happening

• The card only showed a pie of period composition, so spend over time was hard to read.
• The middle period was Yesterday — one day — not a week of calendar days.
• 30-day totals had no day-by-day breakdown on the card.

What this changes

• Period switcher is Today / 7 Days / 30 Days. Existing installs that stored Yesterday land on 7 Days.
• A pie/bar capsule next to the period picker; both choices persist.
• Bar view is one stacked bar per calendar day (idle days stay as a thin stub). Cost and Tokens stack by provider; Cost/MTok is a blended rate per day because rates cannot stack.
• Pie and bars both prefer daily usage history so they share one window; Today still falls back to the spend tile when history is missing.
• iCloud-merged daily series is kept on the rendered snapshot so 7-day bars include peer Macs.
• Share screenshot follows the on-screen chart kind.

Heads-up

• Per-provider Today / Yesterday / Last 30 Days rows are not part of this change.
• 30 Days uses the same history window as Usage Trend (today plus previous days), so the stacked bars add up to the pie.

Tests

• swift test --filter TotalSpendAggregatorTests --filter UsageHistoryAggregatorTests

🟡 Changes recommended

The daily Cost/MTok bar computation can blend across providers that don’t have both cost and tokens on a given day, producing incorrect per-day rates.

Pull request overview

This PR upgrades the dashboard’s cross-provider Total Spend card to support a new stacked daily bar visualization and updates the middle period from Yesterday to a 7-day calendar window, while keeping share-card exports aligned with what’s on screen.

Changes:

• Adds a persisted pie vs. stacked-daily-bars switcher and updates the period picker to Today / 7 Days / 30 Days (with legacy “Yesterday” mapped to 7 Days).
• Extends TotalSpendAggregator to produce a calendar-true daily series (including idle days) and prefer snapshot daily history for both pie and bars.
• Updates share rendering and docs to reflect the new chart modes and period behavior.
