Improve FCM token sync reliability and stale token recovery

---

Note

Medium Risk
Changes FCM token persistence and sync conditions, which can affect subscription state and push delivery if the new comparison/persistence logic misbehaves. Risk is mitigated by keeping the old local token key and only adding a new synced-token marker.

Overview
Improves FCM token rotation/stale-token recovery by separating the latest locally seen token from the last successfully synced token.

SubscriptionManagerFCM.checkChangedPushToken now compares against SYNCED_FCM_TOKEN and triggers a resync when the token is forced, missing, or changed, updating both FCM_TOKEN and SYNCED_FCM_TOKEN only after a successful server sync (with clearer logging and failure reporting). CleverPushFcmListenerService.onNewToken now immediately caches the new token locally and, when a subscription exists, routes the update through getChannelConfig → checkChangedPushToken to ensure the server is brought in sync.

Summary by cubic

Separates the local cached FCM token from the last successfully synced token to improve rotation handling and automatic recovery. Reduces push delivery failures reported in CP-11566 (SWP/Twipe).

• Bug Fixes
  • In SubscriptionManagerFCM.checkChangedPushToken, compare against SYNCED_FCM_TOKEN (new) instead of local FCM_TOKEN; sync when forced/missing/changed; skip only if no token yet; on success update FCM_TOKEN and SYNCED_FCM_TOKEN; clearer logs and errors.
  • In CleverPushFcmListenerService.onNewToken, cache the latest token in FCM_TOKEN immediately (even without a subscription), then load config and call checkChangedPushToken for server sync.

^{Written for commit 64829a4. Summary will update on new commits.}
