fix(auth): request NIP-07 permissions during login and fix retry order (agent)

- Updated `NostrClient.loginWithExtension` to explicitly request `DEFAULT_NIP07_PERMISSION_METHODS` and `DEFAULT_NIP07_ENCRYPTION_METHODS` after retrieving the public key.
- Ensures that encryption capabilities are available immediately upon login, satisfying unit tests.
- Modified `requestEnablePermissions` in `js/nostr/nip07Permissions.js` to attempt structured permission requests *before* the generic `enable()` fallback, aligning implementation with test expectations and ensuring extensions receive the specific scope request.
- `loginWithExtension` now throws if the permission request fails.
