Summary

An account's page now has the Transactions page's search and filters, saved filters, Newest/Largest sort and Outgoing/Incoming tabs. Results cover only that account, at every date, and the URL keeps the state. To share the code, the list moved from pages/budget into a new features/transaction-list slice. Look first at features/transaction-list/index.ts and pages/bank-account.

Motivation

• The account page only offered a plain list with "Show older transactions". It had no way to search, filter or sort.
• Copying the Transactions list would have meant keeping two versions of it in step.

Drawbacks

• The diff is big because files moved. Generic pieces went to shared/ui/list-controls/, shared/ui/{load-error,stale-region}, shared/lib/text/amount-bound and a new shared/routing segment.
• The account page doesn't get the period picker or the charts. It lists every date.

Prior art

• I didn't add another shared/lib module. Steiger's shared-lib grouping limit is 15, so the URL search helpers went into a new shared/routing segment instead.

Notes

• Visual change: the account page now shows the Transactions list controls. Its empty state reads "…on this account" in en and fr.
• API: budget.getMerchants accepts an optional accountId, so company suggestions only list that account's companies.
• Fix: with the amount sort, a day could head more than one group, which gave duplicate React keys and overlapping headers. Each header is now keyed by its first transaction, and the virtualizer by item key. A test covers this.
• Tests: transaction-groups.test.ts gains the duplicate-key case. The period test moved to pages/budget/model/period.test.ts.
• Docs: use/home.mdx, reference/procedures.mdx, docs/engineering/web-app.md, docs/engineering/web-ui.md, apps/web/AGENTS.md and the root AGENTS.md.
• Pre-existing and unchanged here: 5 upcomingPayments/forecastSeries tests fail in a full apps/web run because other test files set TZ. They pass when run alone. This change splits one of those TZ-setting test files into two.
