fix: setup wizard status sync job with exponential backoff

[tanmoysrt]

• at a time queue only 100 sites for checks
• backoff constant is 10 seconds, as long as the retry increases, the next retry will be growing exponentially (current time + 10 x 2^retry seconds)
• max retry set to 18, so mathematically the status check will run for max 30 days
• in team filter, pass the Administrator user's team name instead of just Administrator (🤦‍♂️ mistake)
