Pull request overview

This PR restructures the GitHub Actions CI pipeline for this single-backend repository by separating backend build/test, Sonar analysis + Quality Gate reporting, and Telegram notifications into dedicated jobs, with reusable Python helper scripts for Sonar reporting and Telegram message composition.

Changes:

• Split CI into backend, sonar-backend, and notify-telegram jobs with explicit dependencies.
• Add .github/scripts/sonar_quality_gate_report.py to wait for Sonar CE completion, fetch measures, and publish a Quality Gate summary to the Actions step summary.
• Add .github/scripts/compose_telegram_message.py to compose an aggregated Telegram notification from job results.
