fix: getcandidatesubscriptionid silent auth if no subscription in state (#22124)

## **Description**

Very soon there will be multiple places to opt into rewards, which
requires a small change in the `getCandidateSubscriptionId` controller
function. In that function, we detect a subscription id in via `/ois`
and we don't have a subscription object in our store state, we should do
a silent auth for the account tied to the subscription. This will
(re)populate the store state appropriately.

<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> Perform silent auth during candidate subscription discovery when state
lacks the subscription, try all accounts and set a sensible
activeAccount fallback, reduce opt‑in cache staleness to 1h, and make
invalidation async with token reset; update tests accordingly.
> 
> - **RewardsController**:
> - **Candidate Subscription**: `getCandidateSubscriptionId` now returns
`sids[i]` only if a valid token exists AND the subscription is in state;
otherwise performs `performSilentAuth` for that account.
> - **Auth Flow**: `handleAuthenticationTrigger` iterates all accounts,
captures the first success, and sets `activeAccount` to the first
success or the first account; calls `performSilentAuth(account, false,
true)`.
> - **Cache/Thresholds**: Shorten not‑opted‑in opt‑in status stale
threshold to 1 hour (`NOT_OPTED_IN_OIS_STALE_CACHE_THRESHOLD_MS`).
> - **Invalidation**: `invalidateAccountsAndSubscriptions` is now
`async`, also clears `lastFreshOptInStatusCheck`, and awaits
`resetAllSubscriptionTokens`; consumers updated to `await` it (e.g., 403
path in `getSeasonStatus`).
> - **Safety/Refactors**: Null-safety tweaks (e.g., `ois?.[0]`) and
clearer CAIP coercion logic in perps discount; small readability fixes.
> - **Tests**:
> - Add/expand coverage for multi-account silent auth behavior, active
account fallback, 1h threshold logic, async invalidation with token
reset, and new `getCandidateSubscriptionId` behavior (silent auth when
`sids` not in state).
