[Enhancement] Add health check endpoint monitoring with feature flag auto-disable on degradation

[RUKAYAT-CODER]

Overview

src/store/slices/healthDashboardStore.ts polls service health but does not automatically respond to degraded states by disabling dependent features. When the streaming API is degraded, the app continues offering streaming courses — they fail after a timeout, showing errors to users. Automatic feature flag adjustment during degradation would hide failing features and show static alternatives gracefully.

Specifications

Features:

• Health check results mapped to feature flags in degradationStore
• Streaming API degraded → auto-disable streaming, fall back to paginated content
• Payment API degraded → show 'Payments temporarily unavailable' instead of payment form
• Recovery restores features automatically
• Admin can override auto-disable via remote config

Tasks:

• Define HEALTH_TO_FEATURE_MAP in src/config/degradationConfig.ts
• After each health check cycle, apply feature flags based on service status
• Show user-friendly fallback UI when feature auto-disabled
• On service recovery, re-enable feature flag
• Add unit test for degradation → disable → recovery → re-enable cycle

Impacted Files:

• src/store/slices/healthDashboardStore.ts
• src/store/slices/degradationStore.ts
• src/config/degradationConfig.ts (create)

Acceptance Criteria

• Streaming API health check failure disables streaming feature flag
• User sees static content fallback during streaming degradation
• Recovery enables streaming feature within 60 seconds
• Unit test covers full degradation → fallback → recovery cycle
