This commit fixes a critical race condition where `window.nostr` might not be injected
before the app attempts to use it, causing failures in decryption (subscriptions, hashtags, DMs)
and login flows.
Changes:
- Updated `ensureExtensionPermissions` in `js/nostr/client.js` to verify `window.nostr` existence
even when permissions are cached. If missing, it now awaits `waitForNip07Extension` instead of
returning a false success.
- Updated `ensureActiveSignerForPubkey` in `js/nostr/client.js` to wait for the extension
if permissions are cached but `window.nostr` is missing, ensuring a valid signer is created.
This ensures that the "Performance Analysis" optimization (skipping `enable()` calls based on cache)
does not break functionality when the extension injection is delayed.
