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%).
