Added detailed in-code documentation to `js/services/storageService.js` to explain the `STORE_ACCOUNTS` schema, encryption strategy (NIP-44/NIP-04 fallback), and concurrency handling.
Added `testConnection` to `StorageService` and `testS3Connection` to `r2-s3.js`.
Updated `ProfileModalController` to use the new `storageService.testAccess` method for verifying credentials before saving.
The test logic supports both specific bucket checks (via `HeadBucket`) and general credential checks (via `ListBuckets`).
- Adds `js/services/storageService.js` to manage encrypted connection credentials.
- Implements AES-GCM encryption for payloads using a random Master Key.
- Implements NIP-04/NIP-44 encryption for the Master Key using the user's Nostr signer.
- Provides public API for saving, retrieving, and listing connections.
- Persists data to `bitvid-storage` IndexedDB.
