fix(handlers): await NostrSend calls throughout codebase

Update all NostrSend call sites to properly handle the async nature
of the function now that it returns Promise<void>.

Changes:
- handler.ts: Add async to sendResponse, await nostrSend calls
- debitManager.ts: Add logging for Kind 21002 response sending
- nostrMiddleware.ts: Update nostrSend signature
- tlvFilesStorageProcessor.ts: Update nostrSend signature
- webRTC/index.ts: Add async/await for nostrSend calls

This ensures Kind 21002 (ndebit) responses are properly sent to
wallet clients, fixing the "Debit request failed" issue in ShockWallet.
