feat: Update CI workflows and add configuration for quality tools

[tavanuka]

### Description
This PR tackles the setup of the CI workflow for the test repository to demonstrate the TUnit's capabilities and span of features. It also introduces several enhancements and fixes to the CI workflows:

- Removed the Qodana code quality workflow from the default pipeline and moved it to a separate operation to improve clarity.
- Added concurrency control to cancel in-progress workflows when re-triggered.
- Updated file paths for test results and coverage outputs to ensure consistency across workflows.
- Logged retrieved artifacts and expanded test result paths for better traceability.
- Added a Codecov configuration file with coverage thresholds and integrated Codecov reporting into pipelines.
- Updated Qodana linter configurations and switched to the latest Qodana image version (2025.3).
- Enhanced ASP.NET Core certificate management by trusting the dev certificate and fixing related script issues.
- Isolated app host tests into a separate job to improve modularity.
- Made updates and fixes to address workflow arguments, typo corrections, and restore steps.

seems like the qodana is not working for community edition when included with some ASP.NET projects.
