Shop filters — apply on close, not per click (prod)

Gate 2 9/9 passed (re-run after the follow-up below). Checkbox toggles in the shop multi-select filters now buffer into a local draft — checkboxes flip instantly — and the navigation (server call) fires once, when the dropdown closes (click outside / re-click the trigger), and only if the selection actually changed. “All shops / All stores” is a single-intent action so it still applies immediately. Fixed on all three surfaces sharing the pattern: POS Session history, Reports Summary, and Order Analysis. nix-cafe e9eb5e5, 3 files, no migration.

Follow-up a1e1e63 + 94fb816 — “first click-out didn’t save” fixed. Narong’s report after the ship: the first commit didn’t apply, the second did. Reproduced (~50% of first interactions on a fresh page load): router.push ran its server fetch but the history commit was silently dropped by the Worker runtime — and separately, closing the popover by clicking a preset chip let the chip’s navigation (built from a stale snapshot) wipe the just-committed shop selection. New shared useFilterPush hook: builds every filter URL from the live / pending query string and verifies the push landed, recovering via an escalation ladder (re-push is no-oped by the router, so: router.replace at 1.2s, full navigation at 2.8s — each only if the URL hasn’t moved and no newer intent superseded it). Verified by 4/4 fresh-load first-commits landing and the chip click now keeping both the shop and the preset.
