Enhances unit testing infrastructure

[ricxJr]

Improves the unit testing workflow for Consistem projects by introducing a robust executor that supports database-backed tests and automated environment management.

Key updates include:

• Implements a new unit test runner supporting paginated results and improved error reporting.
• Adds an interface for managing and regenerating test databases directly from the IDE.
• Provides granular control over test execution through new configuration settings, including assertion filtering and legacy rollback support.
• Refines the UI experience by updating branding assets and streamlining test status visualization.

This transition to a modern v2 execution flow resolves previous limitations with gateway timeouts and manual environment preparation.
