MacOS WebEngine not working in deployed package

[SBriere]

Code signing of the webengine (used to display GPS data on a map) doesn't seem to be properly working for now on Mac OS.
Feature has been disabled on Mac OS.

Investigate and fix the issue - maybe related to wrong entitlement or missing signing on some dependencies?

Looking deeper, the issue is with the codesigning flag "--deep" which sign every library in the package. Since we need to put some entitlements on the webengine but don't want to put them on the whole app (since that would make the Apple Gatekeeper complains and not allow the app to run), we need to put them only on the webengineprocess. However, when running the code signing process with the "deep" option afterwards, the signature gets overwritten, and entitlements are lost.

The solution is probably to manually sign every library in the whole package, which is not an easy task considering we are using Qt libs and PySide6 integration with a lot of libraries and dependencies...
