TODO: Optimize fetch_wallet_state to avoid redundant fetches

🟢 Low Priority - Performance optimization

Current Code

# Parse wallet metadata
# TODO this should not always fetch the wallet event
if wallet_event:
    try:
        decrypted = nip44_decrypt(wallet_event["content"], self._privkey)

What needs to be done

• Cache wallet event data to avoid redundant decryption
• Only fetch/decrypt when wallet data changes
• Improve performance for frequent state checks
