Pattern compliance cleanup across features

[cd-rite]

Summary

Systematic cleanup pass to align all features with established patterns (orchestrator pattern, error handling tiers, apiClient usage).

Split from #1925. Detailed tracking in `clientV2/docs/pattern-compliance-todo.md`.

Scope

• CollectionView — error tier fixes (dual display, retry buttons)
• MetaCollectionView — error handling, error capture in top-level fetches
• CollectionMetrics — error tiers, console.log cleanup, optional chaining
• AssetReview — bug fixes (retry no-op, stigRevisions guard, aggressive recent view removal)
• Export components — migrate `inject('worker')` to `apiClient`
• Cross-cutting — hardcoded colors/font sizes, `defineProps` imports, collectionId prop type consistency
• Performance profiling with large collections
