Display a warning icon when no enabled include lists defined 2

[zackcl]

Resolves #1841, resolves #1838

This PR does the same thing as PR #1892 (will be closed if this is merged), but it includes featureFlagSegmentInclusion instead of hasEnabledIncludeList in the response from the api/flags/paginated endpoint. Also, this PR doesn't require updating the current test cases to avoid failures.

Changes made:

• Updated the api/flags/paginated endpoint to include featureFlagSegmentInclusion in the response.
• Updated the selector logic for determining the warning state in feature-flags.selector.ts.
• Modified this.featureFlagService.fetchFeatureFlags() to this.featureFlagService.fetchFeatureFlags(true) in the FeatureFlagRootSectionCardComponent to ensure that flags are re-fetched from api/flags/paginated whenever the user navigates back to the root page.
• Updated the warning tooltip message to "No include lists enabled."
• Updated common-details-participant-list-table.component.html to fix the undefined errors when navigating to the details page.
