[New Feature]: Enable verbose logs in installation validation pipeline

### Description of the new feature/enhancement

Heavily inspired by https://github.com/microsoft/winget-pkgs/issues/341319#issuecomment-3940299852.
I think it would be better if the logs from the pipeline are verbose instead, it would avoid some confusion sometimes with packages that had dependencies on them.

For instance, instead of this:
```
2026-02-03 08:27:25.982 [CLI ] No suitable installer found for manifest Microsoft.VCRedist.2015+.arm64 with version 14.50.35719.0
2026-02-03 08:27:25.983 [CLI ] Terminating context: 0x8a150104 at C:__w\1\s\external\pkg\src\AppInstallerCLICore\Workflows\DependenciesFlow.cpp:129
```

This is better:
```
2026-03-02 16:51:12.883 [CLI ] Architecture Comparator created with allowed architectures: [Arm64]
2026-03-02 16:51:12.883 [CLI ] Starting installer selection.
2026-03-02 16:51:12.883 [CLI ] Installer [Arm64,burn,Machine,] not applicable: Installer locale does not match required locale: Required locales: [en-US] Or does not satisfy compatible match for Preferred Locales: [en-US, en-ID, id]
2026-03-02 16:51:12.883 [CLI ] No suitable installer found for manifest Microsoft.VCRedist.2015+.arm64 with version 14.50.35719.0
2026-03-02 16:51:12.884 [CLI ] Terminating context: 0x8a150104 at C:\__w\1\s\external\pkg\src\AppInstallerCLICore\Workflows\DependenciesFlow.cpp:129
```

### Proposed technical implementation details (optional)

_No response_

Start by tracing the installation validation pipeline and where its current log verbosity is configured. Compare the existing output with the proposed examples; done should mean dependency and installer-selection details are emitted clearly during validation.
