feat: extract business logic into custom React hooks (Phase 3.1)

Refactor components to use custom hooks for business logic, dramatically simplifying component code while improving testability and reusability. Changes: - Create useSealedSecretEncryption() hook - Encapsulates complete encryption workflow - Handles validation, cert fetching, expiry checks, encryption - Built-in error handling with snackbar notifications - Returns ready-to-apply SealedSecret object - Type-safe Result<T, E> pattern - Create useControllerHealth() hook - Encapsulates health monitoring logic - Auto-refresh with configurable interval - Manual refresh function - Loading state management - Proper cleanup - Refactor EncryptDialog component - Simplified from 215 → 130 lines (-85 lines, -40%) - Business logic extracted to hook - Focus on presentation logic only - Much easier to understand and maintain - Refactor ControllerStatus component - Simplified from 115 → 58 lines (-57 lines, -50%) - One-line hook usage - Perfect abstraction example Benefits: - Separation of concerns (business vs presentation) - Reusable hooks across components - Easier to test (hooks testable independently) - Better maintainability (single source of truth) - Code reduction: ~140 lines removed from components Build: 352.05 kB (96.99 kB gzipped), +0.71 kB (+0.2%) Phase 3.1 complete. 8 of 14 phases done (57%).
