fix(ux): confirm modal's Cancel/Confirm were dead on the promise-API path

User report: the Purge Archived dialog ('Permanently delete all
archived items?...') opened, and Cancel did nothing — and Confirm
would have been equally dead, leaving the page stuck behind the
overlay until a reload.

Root cause: confirm.ts wired the modal's buttons ONLY inside the
htmx:confirm interceptor. confirmDialog() — the promise API used by
purgeArchivedItems, remove-account, and other TS call sites — never
wired them. So whenever a page's first confirm interaction came from
the promise path (no hx-confirm element clicked first), both buttons
had no listeners. The 2026-10-30 confirm_probe spec only exercised the
hx-confirm path, which is why it survived.

Fix: wireButtons() now runs at module init (the header renders before
deferred modules) and inside confirmDialog() — both idempotent via the
existing data-wired guard.

Pinned by tests/ui/promise_confirm_probe.spec.ts (no env gating): the
purge POST is route-intercepted, so the probe asserts Cancel closes
the modal and Confirm issues the guarded request without deleting any
dev data. hx-confirm path re-pinned green (confirm_probe with BH_FEED).
Verified manually at 390x844: open -> cancelWired=true -> Cancel
closes -> Confirm fires the intercepted request.
