This change adds comprehensive unit and integration tests to cover:
1. `signerKeyManager.js`: Verification of key derivation from signatures and passphrases.
2. `storageService.js`: Tests for saving, retrieving, and decrypting connections, specifically verifying that generic S3 payloads (endpoint, region, bucket) are preserved alongside R2 payloads.
3. `UploadModal.js`: Integration tests mocking the storage service to verify that R2 connection details correctly map to the UI input fields and that the "Unlock" flow updates the UI state.
It also introduces `fake-indexeddb` as a dev dependency to enable reliable testing of IndexedDB interactions in the Node/JSDOM test environment.
