aksd: DeployWizard: warn when deployment exceeds namespace resource quota

[gambtho]

Summary

The deploy wizard's server-side dry-run validates the Deployment object but not the pods the ReplicaSet controller creates. When a namespace has a ResourceQuota, users could deploy successfully only to find pods stuck in FailedCreate with no prior warning.

• Added checkResourceQuota() utility that fetches namespace ResourceQuotas and compares requested resources against remaining quota
• Shows a non-blocking warning banner in the Deploy review step when resources would exceed quota
• Added shared K8s resource quantity parsers (parseCpuToMillicores, parseMemoryToBytes, formatCpu, formatMemory)

Type of Change

• New feature (non-breaking change which adds functionality)

Related Issues

Fixes #492 (quota warning portion; Map tab fix is in #493)

Changes Made

File	Change
utils/shared/resourceUnits.ts	New — K8s resource quantity parsers and formatters
utils/shared/resourceUnits.test.ts	New — 15 unit tests
DeployWizard/utils/quotaCheck.ts	New — fetches namespace quotas, compares against deployment resources
DeployWizard/utils/quotaCheck.test.ts	New — 9 tests (fit, exceed, replicas, multi-container, RBAC fail-open, mixed docs)
DeployWizard/hooks/useDeployWizard.ts	Added quotaWarnings state + useEffect that runs quota check on Deploy step entry
DeployWizard/components/DeployPure.tsx	Renders quota warning banner (MUI warning.main color)
DeployWizard/components/Deploy.tsx	Passes quotaWarnings through
DeployWizard/DeployWizard.tsx	Passes quotaWarnings through

Design decisions

• Warning, not a hard block — users can still deploy even when quota would be exceeded (the quota may change, or they may know what they're doing)
• Fail-open — if the ResourceQuota fetch fails (e.g. RBAC), no warnings are shown rather than blocking deployment
• Runs on step entry — quota check runs via useEffect when entering the Deploy review step, so warnings appear before the user clicks Deploy
• Replica-aware — multiplies per-pod resources by spec.replicas (uses declared replicas, not HPA max, to keep it simple)
• Checks 4 resource keys — requests.cpu, requests.memory, limits.cpu, limits.memory

Testing

• Unit tests pass — 24 new tests all passing
• TypeScript type check passes
• ESLint passes (0 warnings)
• Prettier formatting passes

Test Cases

1. No quota in namespace — no warnings
2. Resources fit within quota — no warnings
3. Memory request exceeds remaining — warning with specific numbers
4. CPU exceeds remaining — warning returned
5. Replicas multiplied correctly (128Mi × 3 = 384Mi > 256Mi quota)
6. Multiple containers summed correctly
7. Non-Deployment resources (Service, ConfigMap) skipped
8. Fetch failure (RBAC) — returns empty array (fail-open)
9. Mixed docs — only Deployment checked

• I have performed a self-review of my own code
• My changes generate no new warnings
• I have added tests that prove my fix is effective or that my feature works
• New and existing unit tests pass locally with my changes

Pull request overview

Adds advisory ResourceQuota awareness to the DeployWizard review step so users get warned (non-blocking) when their deployment’s pod resources would exceed remaining namespace quota.

Changes:

• Introduces shared CPU/memory quantity parse/format helpers.
• Adds checkResourceQuota() to fetch namespace quotas and compare against computed manifest totals.
• Wires quota warnings through the DeployWizard hook and UI banner.

• The PR description focuses on Deploy Wizard quota warnings, but this PR also updates the Headlamp submodule and includes very large localization churn across multiple locales. To keep review/audit scope clear, consider splitting the submodule + broad localization updates into a separate PR, or explicitly call them out in the PR description as intentional changes.
