SPA: audit the other load-more/filter screens for the async races hardened in #467 #469

PR #467 (stock lot paging/filter) went through 11 codex review rounds, every finding a real interleaving of optimistic inputs, offset paging, and unticketed async settles. The stock panel now follows an intent-ordering discipline: a monotonic ticket per load claimed at user-intent time, checked after EVERY await (success and catch paths), ownership rules for shared loading flags, an applied-snapshot for optimistic inputs (commit on land, rollback on failure), write-result reconciliation against pre-mutation reads, and invalidation at every wholesale-replace or collapse.

The pattern #467 started from — HistoryPage, AuditPage, and the other limit/offset + from/to screens — predates that discipline: their loads are unticketed, so the same stale-settle/mixed-window/late-failure races exist there (e.g. two quick filter changes racing, a late rejection painting an error over a healthy view, load-more mid-filter mixing windows).

Sweep those screens against the checklist above; StockPage.tsx and its 56-test suite in StockPage.test.tsx are the reference implementation. Vitest can reproduce each race with deferred-promise mocks (see the 'codex round N' tests).
