Upgrade MongoDB versions

[junminahn]

Description
Our MongoDB database version has not been updated since the project's inception. We need to verify the current version and assess upgrade possibilities.

Technical Details

• Check the MongoDB version in live environments to identify if a newer version is available.
• Verify the database versions in sandbox environments.
• Develop an upgrade plan and implement it across live environments in sequence: dev, test, and prod.

Definition of Done (DOD)

• All live and local database versions are synchronized.
