refactor: standardize test filenames for fragile-goods

[rockaxorb13]

Summary

This PR standardizes the test file naming convention for the fragile-goods template.

It merges the non-standard logic-minutes.feature and logic-seconds.feature files into a single logic.feature file, refactoring some logic but having no change in functionality which aligns the template with the rest of the repository. This ensures CI/CD tools and test runners can automatically discover and execute these tests.

Changes

• Merged Files: Combined logic-minutes.feature and logic-seconds.feature into src/fragile-goods/test/logic.feature.
• Refactored Logic: - Standardized the Background to use the 10-minute delivery schedule contract.
  • Updated the "Seconds" scenarios to use a delivery duration of 10m 11s (instead of 11s). This preserves the intended "Late Delivery" failure logic while adhering to the 10-minute contract limit defined in the background.
• Cleanup: Deleted the old non-standard feature files.
