fix(audit): frontend HIGHs — surface fetch errors, kill href=#, invalidate queries, toast over alert

R2-H10: webhook-delivery-log and audit-log-list both swallowed fetch
errors silently — failed loads showed spinner forever or stale data.
Both now set a loadError state, show an inline retry banner, and fire
a toast.error. Same applies to audit-log loadMore.

R2-H11: audit-log-card rendered as `<a href="#">` — tapping on mobile
inserted `#` in the URL and scrolled to top (back-button trap).
ListCard now treats `href` as optional and renders a non-link `<div>`
when omitted; audit-log-card no longer passes href.

R2-H12: smart-archive-dialog only invalidated ['clients'] / ['berths']
/ ['interests']. Detail header kept showing Archived=false until hard
reload. Now also invalidates ['clients', clientId] and removes the
['client-archive-dossier', clientId] cache so re-open re-fetches.

R2-H13: client-list bulk mutation used native alert() on partial
failure (blocking the page) and had no onError handler. Replaced with
toast.warning / toast.success / toast.error.

1175/1175 vitest passing.
