[AI-FSSDK] (DO NOT REVIEW) [FSSDK-12248] Increase max retry time interval to 3 secs

[jaeopt]

Summary

This PR increases the maximum retry time interval for event dispatching from 0.2 seconds to 3 seconds by adjusting the backoff factor. This change improves resilience when handling transient network issues or temporary service unavailability.

Changes

• Updated backoff_factor from 0.2 to 1.5 in event_dispatcher.py
• With 3 retries (RETRIES=3), the retry intervals are now approximately: 1.5s, 3.0s, 6.0s
• This provides a maximum retry interval of 3 seconds as requested

Jira Ticket

FSSDK-12248

Testing

• Existing unit tests should continue to pass
• Retry behavior can be verified by simulating network failures or 5xx responses
• The backoff factor change maintains compatibility with the urllib3 Retry mechanism

Notes

• The retry count remains at 3 (unchanged)
• Only the timing between retries has been adjusted
• This change affects event dispatching for all SDK events
