Add earnings analytics: payment tracking + sitter dashboard

[bradburch]

Summary

• New Payments table (migration 0008 + schema.sql lockstep): multiple whole-dollar payments per booking (deposits/partials), recorded by the sitter with method/date/note; deleting a record is the correction mechanism (no refunds/negative amounts by design)
• Repo layer: guarded atomic insertPayment (pending allowed; blocked/cancelled/foreign refused), triple-id-scoped deletePayment, listPaymentsForBooking, PaidTotal join on the bookings list, and getAnalytics (12-month zero-filled monthly revenue, all-time by-service + top-clients, outstanding balances over confirmed bookings)
• Admin routes: POST/GET/DELETE /:slug/admin/bookings/:id/payments, GET /:slug/admin/analytics (camelCase payload + JS-derived tiles), paidTotal on the bookings list
• Frontend: shared PaymentsPanel (list + record form + delete), Bookings rows show paid state with an inline panel, and a new Earnings section — stat tiles, hand-rolled 12-month SVG revenue chart, by-service and top-client breakdowns (all-time), outstanding table with inline payment recording. No new dependencies.

Design spec: docs/superpowers/specs/2026-07-11-earnings-analytics-design.md (committed on this branch).

Test plan

• 307/307 tests across 46 files (new: payments-repo, analytics repo+route, payments-routes)
• typecheck / eslint / prettier / build clean
• Browser-verified: Earnings section render, tiles/chart/breakdowns, record + delete payment round-trip from both Bookings and Earnings, #earnings deep-link, fresh-tenant empty states
• Run migrations/0008_payments.sql against remote D1 on deploy

Known follow-ups (deferred by review)

• Payments on cancelled bookings have no UI surface (API supports deletion; needs a read-only ledger on cancelled rows)
• Analytics endpoint doesn't trigger calendar reconciliation (Bookings page does; 120s TTL)

Code review

No issues found. Checked for bugs and CLAUDE.md compliance.

Four independent review passes over the 19-file diff (head 4bb317c): a shallow bug scan (SQL bind ordering, 12-month window math, route handlers, panel/section logic), a git-history pass (no conflicts with the booking-lifecycle Declined semantics from #21; insertPayment is the only write path into Payments), a prior-PR-feedback pass (consistent with fix patterns from #18/#21/#22: bounded queries, best-effort reconciliation, tenant-scoped guards), and a code-comment compliance pass (Model A invariants hold on the new table and queries). No CLAUDE.md files exist in this repo.
