feat(p2p): Change sync-v2 main loop interval to one second

[msbrogli]

Motivation

The sync v2 main loop already have protection against multiple executions. But it just checks if it is running every 5 seconds per connection. We can safely reduce this interval to 1 second, speeding up the sync.

Acceptance Criteria

1. Reduce the interval from 5s to 1s.
