Decreased delayFactor to default 200 milliseconds and increased maxAttempts from 8 by default to 10 to lover first retry delay and potentially decrease response while survive flood of change requested from scheduled to in progress.

## 📋 Review Summary

This PR addresses an issue where Firestore transactions could fail during re-running failed jobs due to high contention. It correctly introduces a retry mechanism using package:retry and adjusts RetryOptions for more aggressive initial retries, which should improve reliability and performance under load.

🔍 General Feedback

• The use of RetryOptions is consistent across the modified handlers.
• Error handling in rerun_all_failed_jobs.dart was updated from a 200 OK response to an exception, which is more aligned with standard practices for indicating that an operation cannot be performed.
• Consider simplifying the r.retry closures by removing redundant async/await keywords to make the code more idiomatic.
• Minor inconsistency noted between NotFoundException and BadRequestException for similar error states across different handlers.
