Subject: [PATCH] fix(nostr): await nip-07 extension injection to resolve race
 conditions

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.

Verification:
- Confirmed `waitForNip07Extension` is imported in `js/nostr/client.js`.
- Verified `HashtagPreferencesService` already implements multi-scheme decryption and optimistic updates.
- Verified `SubscriptionsManager` implements multi-scheme decryption.
- The race condition fix ensures the signer is correctly initialized with capabilities, enabling the decryption logic to work.
