DLLs are not signed on Windows

Bug report

Describe your environment

• Device: PC
• OS name and version: Windows 11
• IVPN app version: v3.14.17

Describe the problem

It seems that the DLLs shipped with IVPN (at least some of them) are not signed. This creates problems in environments with Smart App Control enabled and also adds security risks.

List of unsigned DLLs I have found so far:

- IVPN Helpers Native x64.dll
- libpcks11-helper-1.dll
- libssl-3-x64.dll
- libcrypto-3-x64.dll

Steps to reproduce:

1. Enable Smart App Control
2. Enroll policy that blocks unsigned binaries
3. Install IVPN
4. Try to connect using OpenVPN or Wireguard

Observed Results:

Cannot use IVPN in environments with Smart App Control enabled.

Expected Results:

DLLs are signed, therefore allowed by policies.
