Track metrics when users manually provide job inputs

Summary

Track metrics in Rails when users manually provide input values to jobs through the UI or API (during job retries).

Proposed Metrics

Track the following in Rails:

1. Count of jobs where users manually provided input values
   • When: User retries a job with inputs
   • Where: UI interaction in Rails
2. Percentage of eligible jobs where inputs were provided
   • Ratio: Jobs with inputs provided / Jobs with inputs configured
