[Bug] License registration fails with "network connection" error due to missing libunistring.so.2 in AppImage (Debian 13)

[dev-aex]

Please answer the questions below, it helps us to keep track of the issue. Please do not ignore it or your issue will be closed.

Note: If the bug is related to data, please attach an example SQL data.

Describe the bug
When attempting to register a license using the Linux AppImage, the application throws a network connection error despite the system having an active and fully functional internet connection.

Error displayed in the UI:

❌ "TablePlus requires a network connection to register device, please check your internet."

Inspecting the terminal logs reveals a missing shared library dependency (libunistring.so.2), which consequently causes a GIO TLS module load failure. This seems to break the app's ability to make the secure HTTPS request needed for license validation.

Which driver are you using and version of it:
N/A (The issue occurs globally during app license activation, before connecting to any database).

Which TablePlus build number are you using (the number on the about screen):
[Por favor, escribe aquí el número de Build que sale en la ventana "About", ej: Build 232]

To Reproduce
Steps to reproduce the behavior:

1. Launch TablePlus via terminal using ./TablePlus-x64.AppImage
2. Go to the license registration window.
3. Paste a valid license key and click Register.
4. See the network connection error popup.

Expected behavior
The application should successfully validate the license key over the network without failing due to missing system or GIO module libraries.

Desktop (please complete the following information):

• OS: Debian GNU/Linux 13 (Trixie)
• Architecture: x86_64
• Version / DE: KDE Plasma 6.3.6 / KWin (Wayland)
• AppImage version or not: Yes (TablePlus-x64.AppImage)

Additional context
I have temporarily disabled my local firewall (UFW) to rule out port blocking, but the error persists. The system is definitely online.

The root cause appears to be that newer Debian 13 (Trixie) environments might have updated/dropped libunistring.so.2, breaking the AppImage's internal network libraries (libgiognutls.so).
