Marc-André Bombeck e060ab33a2 fix(integrations): silence the Withings scope-skip path from the 3-strike alert ladder
The v1.4.26 scope-skip short-circuit in `sync-activity.ts` and
`sync-sleep.ts` called `recordSyncFailure` for a deliberate no-op,
which incremented `IntegrationStatus.consecutiveFailures` and tripped
the 3-strike admin Telegram alert for every legacy connection. Webhook
deliveries (appli=16 / appli=44) could run the counter from 0 to 3 in
seconds on a freshly-deployed v1.4.26 install, and pre-existing
counters that survived the deploy (e.g. an 87-strike row from the
pre-fix transient burst) paged immediately on the first scope-skip
after the 24h re-alert window closed.

Extract a new `parkIntegrationAtReauth` helper next to
`recordSyncFailure` that sets the row to `error_reauth` without
incrementing the counter, without writing an `integrations.sync.failed`
audit row, and without entering the threshold ladder. A standalone
`integrations.reauth_required` audit row is written on the first park
so the operations trail still shows the event; re-parking the same
scope-skip is idempotent (no extra audit write). Swap the two
deliberate scope-skip call-sites in `withings/sync-activity.ts` and
`withings/sync-sleep.ts` to the new helper.

The defence-in-depth 403 catch-block in each sync routine stays on
`recordSyncFailure` — a 403 reaching the catch IS genuinely unexpected
once the scope-skip lands above, so the alert ladder should still fire
on that asymmetric pair. BL-P3-2 parity verified between activity and
sleep.

Tests extended:
- `integrations/__tests__/admin-alert.test.ts` adds a
  `parkIntegrationAtReauth` block asserting state=error_reauth without
  counter increment, no `dispatchNotification`, and audit-log
  idempotency on a second call.
- `withings/__tests__/sync-activity.test.ts` +
  `withings/__tests__/sync-sleep.test.ts` swap their scope-skip
  assertions to `parkIntegrationAtReauth` and keep the 403 catch-block
  on `recordSyncFailure` to prove the defence-in-depth alert path
  survives.
