[WIP] feat: add a method to force sync the syncEngine without deleting the local data

[MojtabaHs]

Based on the very recent conversation in Slack, I found that tearing down and setting up the sync engine forces it to synchronize changes with CloudKit.

I think the underlying issue is likely related to the sync triggers, but this workaround works for now.

Also, to keep a single source of truth, I reused the existing implementation by adding an argument to the existing function instead of introducing a separate code path.

Please take a look, test, and let me know what you think.

Update:
more aggressive testing shows that it can leave triggers dangling and throw:
SQLite error 1: no such trigger sqlitedata_icloud_after_primary_key_change_on...

The data also becomes unstable, showing different states after each refresh.
