perf: introduce offline sync event limit

[isekovanic]

🎯 Goal

Implements this spec.

Since most other stuff is already supported by the SDK, here we introduce:

• A way to limit the number of sync events we want to go through (regardless of what number the server returns)
• We anyway still do queryChannels so this just prevents additional DB pressure if we get many, many events
• The default stays at 250
