🤖 Pull Request summary

Adds configurable SonarQube platform selection to build actions.

• New input parameter: Added sonar-platform input (next/sqc-eu/sqc-us) with "next" as default across all three build actions
• Dynamic vault path resolution: Replaced hardcoded "next" vault paths with conditional logic mapping platform values to vault keys (sqc-eu→sonarcloud, sqc-us→sonarqube-us, next→next)
• Poetry action enhancement: Added SonarQube environment variables (currently commented as disabled in build script)

Review focus: The nested ternary expressions in vault secret paths are complex and error-prone - consider extracting to a separate step for better readability and testing.
