Expand admin-sales-summary with Ultra + products breakdown

[shanerbaner82]

Summary

• Expands Admin MCP admin-sales-summary so attributable inbound dollars include Ultra (Cashier Max/Ultra) subscriptions, plugin sales, and first-party product sales — not only PluginLicense + Anystack license counts.
• Adds breakdown, by_product, ultra (active / comped / window revenue), comped counts, all_time + days up to 3650, and keeps plugin_license_revenue / top_plugins / Anystack license fields for compatibility.
• Documents that Cashier subscriptions.price_paid is overwritten on invoice paid (renewals do not create rows), matching Filament SubscriberIncomeChart.

Caveats

• Ultra renewals: price_paid is latest invoice total only; window revenue under-counts renewals.
• Comps / $0: excluded from paid revenue; counted under comped.
• Ultra ≠ Anystack policy: plan key max is named Ultra and lives on Cashier subscriptions.

Test plan

• php artisan test --filter=AdminSalesSummaryTest
• Pint on dirty files
• Manual MCP call with days / all_time against staging or local admin OAuth (optional)
