Empty dbConnections array in openedge-project profile are not used

[kenherring]

Fixes #523

[Copilot]

Pull request overview

This PR addresses issue #523 in the OpenEdge project profile parsing used by the VSCode ABLUnit Test Runner, ensuring that an explicitly empty dbConnections array in an openedge-project.json profile is respected (instead of inheriting parent/default DB connections).

Changes:

• Update OpenEdge project profile merge behavior to distinguish between “unset” vs “explicitly empty” dbConnections.
• Add/extend integration and unit tests plus new test fixtures to validate DB connection inheritance/override behavior.
• Bump extension version and update changelog for the new pre-release.
