Description
Added kubernetes-dashboard helm chart (v7.3.2) with resource limits based on actual usage monitoring from dev-cluster. Fixes critical issue where Kong gateway has no resource limits (BestEffort QoS).

Benefits

• Fixes Kong BestEffort QoS by adding resource limits for the first time
• Reduces total resource requests from 500m CPU / 1000Mi memory to 90m CPU / 437Mi memory
• Provides appropriate headroom (10-25x) over actual usage (6m CPU, 171Mi memory)
• Prevents resource over-provisioning while maintaining stability

Possible drawbacks

• Currently configured based on dev-cluster usage patterns
• Other clusters may need adjustments based on their specific workloads

Applicable issues

• Related to infrastructure resource optimization
• Addresses Kong missing resource limits issue

Additional information
Chart: kubernetes-dashboard v1.0.0 | App: v7.3.2

Resource Changes:

• Auth/API/Web/Metrics: 100m/200Mi → 10m/64Mi requests, 250m/400Mi → 100m/256Mi limits
• Kong: None → 50m/181Mi requests, None → 100m/256Mi limits (CRITICAL FIX)
