Two root causes for "Blossom set as default but not showing / not usable":
1. SAVE required unlock. saveConnection throws "Storage is locked" without a
master key — but Blossom has no secret. Added
storageService.saveKeylessConnection() (writes plaintext meta, no encryption,
no unlock) and the Blossom save branch now uses it. So a Blossom connection
saves even if the user never unlocked storage.
2. UploadModal treated Blossom like a locked S3 connection: it only set
activeCredentials when isStorageUnlocked, showed "Locked 🔒", blocked the
file-pick behind an unlock prompt, and mislabeled it "S3 Compatible". Now:
getProviderLabel → "Blossom"; loadFromStorage resolves servers from the
plaintext meta (no unlock); the summary shows "N servers / Nostr-native"; the
two upload gates and updateLockUi bypass unlock for Blossom
(activeProviderIsBlossom). Uploads authorize with the Nostr signer instead.
Bumped UploadModal size baseline (+gating code). Lint + build clean. Local only.
