chore: Upgrade Dependencies

[Hariom01010]

Description

We are performing a dependency upgrade across the codebase. The goal is to align outdated packages, remove deprecated dependencies, and ensure compatibility with the current tooling and framework versions while keeping the application stable.

Key dependencies requiring attention:

• ember-source
• ember-cli
• ember-data
• ember-addons

Current Behavior

• Multiple Dependencies are outdated
• Dependency upgrades introduce build or runtime errors

Expected Behavior

• All dependencies are upgraded to compatible and supported versions
• No build, runtime, or CI errors after the upgrade
• Application behavior remains unchanged and stable after the upgrade
