Cuong Manh Le 35e2a20019 Refactor handleRecovery method and improve tests
- Split handleRecovery into focused helper methods for better maintainability:
  * shouldStartRecovery: handles recovery cancellation logic
  * createRecoveryContext: manages recovery context and cleanup
  * prepareForRecovery: removes DNS settings and initializes OS resolver
  * completeRecovery: resets upstream state and reapplies DNS settings
  * reinitializeOSResolver: reinitializes OS resolver with proper logging
  * Update handleRecovery documentation to reflect new orchestration role

- Improve tests:
  * Add newTestProg helper to reduce test setup duplication
  * Write comprehensive table-driven tests for all recovery methods

This refactoring improves code maintainability, testability, and reduces
complexity while maintaining the same recovery behavior. Each method now
has a single responsibility and can be tested independently.
