Adding version to eco-ci v3 endpoint

[ArneTR]

Greptile Overview

Greptile Summary

Added version field to the Eco CI v3 endpoint to track client version information. The change extends the existing database migration and API implementation that previously added os_name, cpu_arch, and job_id fields.

Key changes:

• Added version field to CI_MeasurementV3 model as optional string
• Updated database schema in structure.sql and migration file to include version column
• Modified INSERT query to include version in the correct parameter order
• Added test coverage with version: 'v2.2' in MEASUREMENT_MODEL_V3

Issues found:

• Outdated documentation comments incorrectly state that v3 fields are "not stored" when they are now persisted to the database
