fix: correct tag handling in dbNodeFromCode

[akashrajeev]

Fixes #821

Summary

This PR fixes incorrect tag handling in dbNodeFromCode in application/database/db.py.

Tags were being joined from an empty variable instead of code.tags, causing them to always be stored as empty even when values were present.

Changes

• Updated tag join logic to use code.tags

Impact

• Fixes loss of tag metadata for Code nodes
• Improves correctness of stored data and related features

Testing

• Verified locally that tags are now stored correctly
• Confirmed no regressions in existing functionality
