Fix OpenSSL versions mismatch

[drslebedev]

Summary

Updating to the following gnuradio4 commit causes a segfault in the qa_gnuRadioWorker test:

• FileIO commit: fair-acc/gnuradio4@f3a6529

Observed behavior

• CI test run crashes with a segmentation fault in qa_gnuRadioWorker after bumping to the commit above.

Current hypothesis
We suspect this is related to the newly introduced dependency:

• libcurl4-openssl-dev

There may be an incompatibility between system libcurl/OpenSSL and the custom OpenSSL build used by opencmw (required for HTTP/3, prior to Ubuntu 25.10). The crash appears after introducing a system component that expects system OpenSSL behavior/ABI while opencmw brings its own OpenSSL build.

Proposed direction / fix strategy
Move towards using system OpenSSL everywhere and remove the custom OpenSSL build from opencmw-cpp. This requires aligning the entire stack (docker image, yocto, dependencies) to a consistent OpenSSL + dependecies library set.

Work plan / required changes

1. Update gnuradio4 Docker image to Ubuntu 25.10
   Add dependencies: libngtcp2-dev, libnghttp2-dev, libnghttp3-dev
   PR: Docker: bump to Ubuntu25.10 gnuradio4#694

2. Update Yocto image to include required libraries
   Status: done -> to be deployed

3. Update opencmw-cpp to use system OpenSSL (remove custom OpenSSL build)

   • Replace custom-built OpenSSL with system-provided OpenSSL packages
   • Run tests using the updated Docker image
   • Note: GitHub runners do not provide Ubuntu 25.10, so tests should run in Docker

4. Update gr-digitizer to latest gnuradio4 + fix regressions

   • Address issues introduced in Introduce Value, Value::Map and Tensor everywhere gnuradio4#692
   • Ensure build and tests pass with the new dependency stack

5. Update OpenDigitizer to latest dependencies

   • Bump to latest gnuradio4, updated opencmw-cpp, and updated gr-digitizer
   • Verify integration tests and deployment configs
