Vehicle template selection does not render correctly on linux HiDPI displays when not using a uv created venv

### Is there an existing issue for this?

- [x] I have searched the existing issues

### Description of the bug

My monitor is 4K, with 3840x2160 resolution. I use 200% scaling in Cinnamon (so Linux Mint users with HiDPI monitors will likely also be affected). GUI doesn't render fonts in some selector windows correctly.

### Steps To Reproduce

1. Buy 4K monitor
2. Set HiDPI/scaling to suit the tiny pixels and make everything readable and pretty
3. Run `ardupilot_methodic_configurator`
4. Click "Skip FC connection.."
5. Click selector under "Source Template directory:"
6. Observe incorrectly spaced text and obscured text

If I set display scaling back to 100% (which makes everything look tiny), then that selector renders correctly.

### Expected behavior

Ideally `ardupilot_methodic_configurator` would play nice with HiDPI/Scaled displays. I realise this may not be easy with the chosen GUI software.

### Screenshots / Logs

Fonts in the template selection screen look like this:
