[Quality Management] Enhance error messaging for test value type changes and improve validation logic

[JakovljevicDusan]

What & why

Existing code suggested that there is actionable error message, while it was regular error message. Enhance that experience with basic actionable error message, and clean-up code.

Flaky test re-enabled without evidence of fix

The comments "Test disabled due to inconsistent behavior across environments" and the reference to Bug 613059 were removed, re-enabling ApplicationAreaMgmt_IsQualityManagementApplicationAreaEnabled. If the root cause tracked by Bug 613059 was not resolved as part of this PR, the test will continue to be flaky and may cause intermittent CI failures.

Recommendation:

• Only remove the disabled comments if Bug 613059 has been verified as fixed. Add a comment referencing the fix commit or work item that resolved the instability, so reviewers can confirm the test is now stable.

// Re-enabled after fix for Bug 613059 (resolved in <commit/workitem>)
[Test]
procedure ApplicationAreaMgmt_IsQualityManagementApplicationAreaEnabled()
