Subject: [PATCH] Add ensemble.storage.clear() method

Adds a clear() method to ensemble.storage that removes all normal
storage values while preserving encrypted storage (enc_ prefixed keys),
secure storage, keychain values, and system storage.

Changes:
- PublicStorage mixin: add getKeys() and clearPublicStorage()
- EnsembleStorage: add clear() method with UI binding dispatch
- Register 'clear' in EnsembleStorage.methods()
- Add unit tests for the clear logic

Fixes #2187
