feat(admin): add Billing tab and dashboard page (TASK-828) (#267)

* feat(admin): add Billing tab and dashboard page (TASK-828)

Surfaces the Pad Cloud billing metrics in the admin console as a new
tab between "Audit Log" and "Settings". Final piece of PLAN-825.

The page calls GET /api/v1/admin/billing-stats (TASK-827) and renders
six metric cards in a responsive auto-fit grid:

1. MRR              (Stripe-derived; greyed when unavailable)
2. ARR              (Stripe-derived; greyed when unavailable)
3. Active Subs      (Stripe-derived; greyed when unavailable)
4. Customers/Plan   (LOCAL — always real; e.g. "Free: 42 · Pro: 7")
5. New Signups 30d  (LOCAL — always real)
6. Churn 30d        (Stripe-derived; greyed when unavailable;
                     subtitle shows cancelled count)

Two banners drive the degraded-state UX:
- cloud_unreachable=true  → amber warning ("sidecar unreachable, showing
                            local data only")
- stripe_configured=false → blue info banner explaining that Stripe
                            metrics will be zero until STRIPE_SECRET_KEY
                            is set on pad-cloud (the expected pre-launch
                            steady state)

Header carries a Refresh button (re-fetches without unmounting the page)
and an "Open in Stripe Dashboard ↗" external anchor (rel=noopener).
A subtle footer renders "Updated just now" or "Updated N min ago" from
the cache_age_seconds field.

The Billing tab is hidden from the layout's tab list when
adminStore.stats.cloud_mode is false — self-host operators won't see a
tab that always 404s on click. Used $derived(...) for the tabs array so
the tab list reacts to the cloud_mode flag flipping after stats load.

Svelte 5: runes throughout ($state, $derived, $props), single onMount
for the initial fetch, no combined effect-on-effect chains (CONVE-606).
Visual idiom mirrors the existing /console/admin stats-bar (.stat
cards, --bg-secondary background, --radius-lg, value/label sizing).

Validated with the svelte MCP autofixer (clean) and `npm run build`
(clean, page emitted to entries/pages/console/admin/billing).

Closes PLAN-825's UI work.

* fix(admin): add role=status / aria-live=polite to Stripe info banner

Codex round 1 LOW: the warning banner already carries role=alert because
its message is urgent (sidecar unreachable), but the "Stripe not
configured" info banner appears asynchronously after load with no live-
region semantics, so screen readers never announce that the page is in
a degraded state. Add role=status + aria-live=polite so the announcement
is non-interrupting but happens.
