Improving the security and reliability of the Windows implementation

[Yashkush06]

Hi! I've been exploring TwinDesk and would love to contribute.

I'm particularly interested in improving the security and reliability of the Windows implementation.

I noticed PR #139 introduced DPAPI-backed storage for the Windows TLS identity passphrase. I couldn't find dedicated regression tests for the identity storage and legacy plaintext migration logic.

Would you be open to a small test-focused PR covering:

DPAPI encryption/decryption

Legacy plaintext migration

safeStorage unavailable fallback

Handling invalid encrypted data safely

I'd like to start with a focused contribution and follow the project's existing testing conventions.

Thanks for maintaining such a great project!
