* feat(sync)!: remove compatibility with v2.29
* feat(sync)_: add AC notifications when initiating the sync fallback
Needed for https://github.com/status-im/status-desktop/issues/15750
Adds an AC notification when the syncing fails and the user is prompted to use a seed phrase instead.
There is one notification for the initiator (created) and one for the old account (received).
Once the flow is completed, ie the receiver presses Enable and sync, the notifications are deleted
